wireless - Ubuntu 14.04, problem installing package skype: i386

I have some problems with my Ubuntu 14.04. I can get both wireless and wired Internet with it. It is also very slow to start. When I performed any actions like update, upgrade or install, it will show me this message.

W: You may want to run apt-get update to correct these problems
E: The package skype:i386 needs to be reinstalled, but I can't find an archive for it.

How can I solve those issues?

Ubuntu root can't give any permissions?

Information about my Ubuntu:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.5 LTS
Release:    16.04
Codename:   xenial

I have a problem. I can't give any permissions nor change them as a root (sudo su, sudo -i etc). What should I do? How do I find the cause of this? How to fix it?

sudo nano test.sh

Output: Error writing lock file ./.test.sh.swp: Permission denied

Giving an user account its own permissions:

sudo chown -R student121:student121 /home/opilane121/

Output: Tons of Operation not permitted texts

Answer to comments:

1) NFS4 is read-write only

2) Output of mount | grep home:

mount | grep home
10.16.122.2:/data/users/students on /home type nfs4  (rw,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,po    rt=0,timeo=14,retrans=2,sec=sys,clientaddr=10.16.122.146,local_lock=none,addr= 10.16.122.2)

The NFS-server is probably running with root_squash:

Very often, it is not desirable that the root user on a client machine is also treated as root when accessing files on the NFS server. To this end, uid 0 is normally mapped to a different id: the so-called anonymous or nobody uid. This mode of operation (called 'root squashing') is the default, and can be turned off with no_root_squash.

It basically maps root to a different user with least privileges. This is the default setting on NFS.

Talk with you server administrator, or if you are the server administrator, add option no_root_squash to the /etc/exports on the server.

How to upgrade a remote server from 8.10 to newer version?

I have a remote server still running Ubuntu 8.10 9.04 that I can only access via SSH.

If I run apt-get update I get a bunch of 404 errors on the packages. I've asked a few questions on Server Fault but got nowhere. Here's what I've done:

1. Run apt-get update which returns errors like:

   
   

   
   

   Err http://gb.archive.ubuntu.com intrepid/main Packages
   404 Not Found
   [and same for many other packages]

   
   




2. Run do-release-upgrade which returns:

   
   

   
   

   Checking for a new ubuntu release
   Failed Upgrade tool signature
   Failed Upgrade tool
   Done downloading
   extracting 'jaunty.tar.gz'
   Failed to extract
   Extracting the upgrade failed. There may be a problem with the network or with the server.

   
   




3. Edited /etc/update-manager/release-upgrades and changed from Prompt=normal to Prompt=lts (as suggested here). Running do-release-upgrade after this returns:

   
   

   
   

   Checking for a new ubuntu release
   current dist not found in meta-release file
   No new release found

   
   




4. (Updated) I have followed the advice in this question and changed /etc/apt/sources.list to refer to jaunty instead of intrepid. However, that distro is not online anymore either. A comment there says I have to upgrade in chronological order...

So basically, it seems like I cannot upgrade because my current distro is out of date and not supported. Is there a way to upgrade direct to 10.x or 11.x? Note, as this is a server I only have command-line access.

UPDATE 24/11: I have managed to upgrade from 8.10 to 9.04. Ubuntu's EOL Upgrades page provides some alternate URLs for apt sources. I also needed to update /var/lib/update-manager/meta-release to point to the old-releases server too.

However, now I cannot upgrade from 9.04 to 9.10. Running do-release-upgrade produces the same error as #2 above, except it "Failed to fetch" (the URLs in meta-release are valid). The Ubuntu Jaunty upgrade page says it's necessary to upgrade using a CD image. I followed the instructions here, but it didn't work:

A fatal error occurred

Please report this as a bug and include the files
/var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log in
your report. The upgrade is now aborted. Your original sources.list
was saved in /etc/apt/sources.list.distUpgrade.

OSError: [Errno 2] No such file or directory: './plugins'

It does say to report the bug, but since this is an old unsupported release I don't know if it's worth doing. However, is there a way round this, to upgrade from 9.04 to 9.10 (And then finally to 10.04 LTS.)

Update from 'Ubuntu Server 9.04' (Jaunty) to 'Ubuntu Server 10.04 LTS' (Lucid).

based on:

https://help.ubuntu.com/community/LucidUpgrades

http://echenh.blogspot.com/2010/04/how-to-upgrade-ubuntu-server-904-to-910.html

Step 1: install update-manager-core

sudo apt-get update && sudo apt-get upgrade
sudo apt-get install update-manager-core

Step 2: Update from 9.04 (Jaunty) to 9.10 (Karmic)

edit /etc/apt/sources.list to replace "jaunty" with "karmic"

sudo apt-get update
sudo do-release-upgrade

Step 3: Update 9.10 (Karmic) to 10.04 LTS (Lucid)

edit /etc/update-manager/release-upgrades and set Prompt=lts

file should (at minimum) contain:

[DEFAULT]
Prompt=lts

edit /etc/apt/sources.list to replace "karmic" with "lucid"

sudo apt-get update
sudo do-release-upgrade

Cant boot Ubuntu alongside windows 10

I tried to install ubuntu on this notebook: http://www.mediamarkt.nl/nl/product/_peaq-pnb-s1415-i1n1-1438850.html alongside windows 10. First i couldnt get in the boot-menu but i know how to get there via system (in the meantime) but now i set windows on the bottom of the list, but it still overulls my ubuntu installation. Everytime i restart this notebook it goes straight to windows. I disable fast boot also, but nothing works.

I have it installed on 3 different pc's with windows 10 as well but i can't mannage to do it this time. Can someone help me?

drivers - Ubuntu 16.04 NVIDIA Prime not showing up

I am having issues with NVIDIA X Server Settings. I will try to put as much info as possible, but if anything is missing let me know and I will add it. I am new to Linux so I might be making mistakes.

Problem:
I can select NVIDIA Prime in the settings. The reason I need this is because I have an integrated Intel GPU and an NVIDIA GPU (quadro K1100M). I need to select my NVIDIA in order to work with Driveworks. Samples won't compile with my integrated Intel.

What I have tried so far:

sudo apt purge nvidia*  
sudo reboot  
sudo add-apt-repository ppa:graphics-drivers/ppa 
sudo apt update
sudo apt install nvidia-390 nvidia-prime

sudo reboot

This resolved nothing

sudo apt purge nvidia*  
sudo apt purge cuda*  

And then install Driveworks. This comes with CUDA so should also come with the drivers (I presumed). This did not solve it either.

Select other drivers from the additional drivers tab. I have tried them but they don't solve anything.

sudo apt-get install nvidia-390 nvidia-prime

Also did not work.

In BIOS I changed an option so that it is possible to switch (can't remember exactly what I changed, but there was a graphics card option I had to select). Didn't help either.

I hope someone is able to help me further. Thanks in advance.

Please install CUDA by following script:

wget http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/cuda-repo-ubuntu1604_9.0.176-1_amd64.deb
dpkg -i cuda-repo-ubuntu1604_9.0.176-1_amd64.deb

apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/7fa2af80.pub
apt-get update
apt-get install -y cuda-9-0 nvidia-prime

customization - Making my own custom Ubuntu

I was wondering, is it possible to make my own customized version of Linux based on Ubuntu 10.10 ?

I am thinking of calling it something different but I was wondering besides making a custom Live CD I am talking about an Linux that people can install on there computers using Ubuntu installation method.

I want to base it on something other than GNOME but be able to install it latter on.

Thanks in advance,

Benny

Currently I am using 'Dekko' as my multi client email tool on my Ubuntu Touch tablet and phone. I know that it is no longer under support, both Touch and Dekko, but what options are out there for a supported multi email client on Touch?

Upgrade from 13.04 to 14.04

I have Kubuntu 13.04 (unsupported release), and want to upgrade it to 14.04.
When I'm trying to run do-release-upgrade I got this error:

Traceback (most recent call last): File
"/usr/bin/do-release-upgrade", line 123, in
"%(url)s\n") % { 'url' : url }) ValueError: unsupported format character '?' (0xa) at index 55

I know that I should upgrade to 13.10 first. I read the documentation, but when I tried to add old-releases repository to my sources list, something like deb http://old-releases.ubuntu.com/ubuntu/ raring main restricted universe multiverse I get 404 error while updating my sources.

Is this documentation too old to help me? Where can I find newer docs? Or can you show me other way to upgrade my OS?

Ralink RT 3290 Bluetooth Problem on Ubuntu 16.04

I have wifi and Bluetooth modules RT3290. Wifi is working fine but Bluetooth is shown as disabled under Bluetooth settings. Can anyone help me fix this?

Ubuntu 14.04 will not boot

I went to start my laptop and it will not boot the operating system. The OS is Ubuntu 14.04 and is the only OS on the laptop. It has been installed on there for over a year. Regular updates have been carried out (but none were carried out the last time it was successfully used). When powering on the laptop the following happens:

1. Normal Packard Bell/Bios splash screen displayed


2. A screen presenting me with the option of starting Ubuntu or a memeory test, defaulting to Ubuntu after 30 seconds (I don't normally get this screen?) - I select Ubuntu


3. This image is what appears on the screen and I get stuck there

That screen means you are having a kernel panic and it is likely during your system last update something went wrong with the kernel. it probably didn't generated initram-disk correctly and therefore the kernel goes into panic mode during boot.

If you were just typing a few words from your screenshot you will find plenty post where people had similar issues as yourself.

Here is one of the posts for example on this same forum:

  http://askubuntu.com/questions/509514/ubuntu-14-04-doesnt-boot

you can follow the instruction and restore back your system.

If you encounter any troubles you can post your queries here again then we can help.

Changed password - now can't login to my account (full disk encyption + encrypted home folder)

So I'm running Ubuntu 15.10. I have full disk encryption setup and an encrypted home folder, I realize this is stupid but I didn't realize what I choose when I set it up and never bothered to try and change it.

So yesterday, via terminal I changed my account + root password. I then tried to start the computer this morning, I get to the account login page, I try to login...it flashes and then goes back to the login page. I understand this is because my home folder can not be decrypted.

I found some guides on line to handle this [ can't log in after password change (ecryptfs) ] however, I can't boot into linux because of the full disk encryption.

I have all password (old + new) and I have the long string passphrase (that I think goes with the full disk encryption).

I really would appreciate your help. I have really important information on this laptop and I haven't backed up in a couple months.

For completeness' sake, I post the solution we found during our conversation in the comments section as an answer:

First of all, you are probably able to boot into your Linux system, you may just not be able to log in graphically, since graphical login usually tries to read/write in your home directory. You can still try to log in using a virtual console (Ctrl + Alt + F1) and work from there.

Using a Live CD instead should also work. You can mount your encrypted system partition from the Live CD, too. For example, you can run gnome-disk-utility on your Live CD and decrypt+mount your system partition from there graphically.

Also, watch out that the instructions in the linked tutorial assume that you are logged in as the user whose home you want to rescue. If you are logged in as another user (e.g. root), then replace the command

ecryptfs-rewrap-passphrase ~/.ecryptfs/wrapped-passphrase

by something like

ecryptfs-rewrap-passphrase /home/[the-user-you-whose-home-you-want-to-rewrap]/.ecryptfs/wrapped-passphrase

or (on a Live CD) by something like

ecryptfs-rewrap-passphrase /[wherever-you-temporarily-mounted-the-home-partition]/[the-user-you-whose-home-you-want-to-rewrap]/.ecryptfs/wrapped-passphrase

lubuntu - Alternative to Wubi Installer (without cd/usb install)

I'm using a old computer and I'm interested in getting linux on it.

My computer cannot boot from USB or CD. I was presented with Wubi but I was just wondering, is there any other way to install Ubuntu (or actually, xubuntu or lubuntu) on my computer without having to manually repartition and stuff. Like have the normal cd/usb install but without a cd/usb

(P.S. I don't need to dual boot windows and linux)

How can I do a full image backup of my system?

I'm looking for a solution to create an exact copy of my system that I can restore in case of hard disk failure by simply putting a new hard drive and restoring from the backup. Something like Acronis TrueImage.

I'm not interested in file based backups, although it'd be a plus.

12.04 - Can I mix sources from different ubuntu versions?

As we know that we are using Repositories for installing packages and repositories configuration file located at /etc/apt/sources.list.

I am using Ubuntu 12.10 (Quantal Quetzal) which reaches End of Life. That means no updates or support. So, the question is, can I use sources.list file from another version, say Ubuntu 12.04 LTS, and will it negatively affect the system.

That seems to be a reproducible issue on Xenial as well as Bionic. The package dropbox which is being provided by Dropbox's repository has some weird dependency tree since output of apt rdepends dropbox is

dropbox
Reverse Depends:
  Conflicts: nautilus-dropbox

  Depends: nautilus-dropbox

Here dependency is also the conflicting package which I think is weird and needs to be corrected from Dropbox's end.

The package nautilus-dropbox is also available in Ubuntu's Multiverse repositories. So, I'd recommend you to remove Dropbox's repository.

First of all determine which file has Dropbox repository's entry using:

grep dropbox /etc/apt/sources.list /etc/apt/sources.list.d/*.list

Edit that file with sudo privileges and some text editor, for example, nano, and put a # to comment the line. To edit run:

sudo nano /path/to/file

Update APT's cache and install nautilus-dropbox:

sudo apt update

sudo apt install nautilus-dropbox

If you want to use Dropbox daemon, install missing library using

sudo apt-get install libatomic1

64 bit - Ubuntu 11.10 and ATI/AMD Radeon 5650

I have a laptop with freshly installed Ubuntu 11.10 and ATI 4200/AMD Radeon 5650 hybrid graphics. The problem is that I can't switch between integrated and discrete video while using Catalyst driver (ver 12.2). Catalyst tells me that I can switch on to discrete on next reboot but after that, the laptop still uses integrated video.

Additionally, my whole system is very slow when I'm using the Catalyst driver.

How can I solve this problem?

Just got it working here (Ubuntu 12.04 64-bit) for the first time since I bought this damn HP Pavilion 4045ea.

I removed every single iteration of fglrx, installed the ATI binary driver from the Software Centre, rebooted and ta-daa!

Unity looks better, full HD movies are finally playable and the whole system seems to be running better.

partitioning - Partition splitting during installation

I already have a Ext4 partition on my hard drive. During Ubuntu's installation the setup shows me an option to split a partition. Apparently I am being forced to define a new partition, but I just want it to install Ubuntu in my already existing Ext4 partition. How do I do this?

Edit: I've taken a picture of my advanced installation screen. sda1 is where my Windows installation is, sda5 and sda6 are the linux partitions I already have. sda7 is my data partition. I'd like to install Ubuntu in sda6, without messing up my windows installation or the data in sda7. What do I have to do?

live usb - Increase persistent file size to greater than 4 gigabytes

My USB's 16 GB, but I only get to use 4 GB in persistence file. Any way to increase it?

Take a look at http://www.pendrivelinux.com/create-a-larger-than-4gb-casper-partition/. The tutorial is for an older version of Ubuntu but works fine for 10.10 and 11.04.

The reason why a separate partition must be created is because the USB creator only makes one partition by default (FAT32 filesystem). Onto that partition it copies the CD or ISO contents and creates a persistence file (ext2 formated) called casper-rw. Since FAT32 can't hold larger then 4GB files the persistence file can't be any larger then 4GB.

13.04 - What is managing SSH keys in Unity, and how do I reset / disable / configure it?

I'm using Ubuntu 13.04, and recently changed my ssh keys. For some reason Unity, or something in Gnome (seahorse?) doesn't seem to be recognizing it. The keys were generated on a different machine, and I basically copied the new SSH key pair to /home/user/.ssh

Something broke after I copied the new keys over. When I run git clone in a terminal in Unity, I get this error:

Agent admitted failure to sign using the key
Permission denied (publickey).
fatal: could not read from remote repository
Please make sure you have the correct access rights
and the repository exists

By chance, I switched to a tty console and ran the same git clone command. It actually works! Is something in Unity is somehow managing the ssh keys, and somehow it isn't using the key pair in the /home/user/.ssh directory?

After some googling, I've tried running ssh-add but it doesn't work. I've also tried moving everything out of the /home/user/.local/share/keyrings directory then rebooting, but I'm still getting the same error in the terminal session in Unity.

What could be the issue here?

Login loop, can only login as Guest. Ubuntu 12.04

My computer wont allow me to login unless its as guest.
I have pressed Ctrl+Alt+F1 and can login using my administrator account there, but not in the normal interface.
I have done updates and upgrades from the terminal, and also tried to create a new admin user, and assigned the user to the same group as the administrator account, but cant login to that user either from the normal login screen.

When I login the screen flashes black and then returns to the login screen
Is there a way to view an error log file to see what the error is that is returning me to the login screen?
How can I do this to figure out what the problem is?

I have also followed instructions on this page Ubuntu gets stuck in a login loop.

It looks like a similar problem, but the fix did not work for me :(

I would like to get back into my admin account and my programs but I am stuck in guest

disk management - How do I give Ubuntu more space (when installed inside Windows 7 (via wubi))?

I had installed Ubuntu inside Windows XP but then I formatted XP and installed Windows 7.

EDIT1: I used Wubi for the same.
I want to know which one of the two will solve my problem? creating a virtual disk or resizing root? Also is resizing root possible as the 4GB ext4 partition is already in a NTFS format Hard Drive partition.

At the time of installation I had allocated only 4GB of space to Ubuntu. I want to increase that size as I keep getting a low disk space notification.

I have surfed through a lot of similar questions but this is not a duplicate.

Because I want to know a little about the file systems. In order to solve my problem,do I have to increase the size of root.disk? Or will it be solved by creating a virtual disk?

Also I want to know the difference between creating a virtual disk and just increasing disk space of root.I'm new to Ubuntu so I don't know how the file systems function.

EDIT2:I have created a virtual disk of 10gb ,but I'm still getting the same notification.Is there anyway to install all further applications on the virtual disk I created?

Additional virtual disks are only useful if you're able to split the filesystem (eg putting /home/ on it) so aren't much use if you've installed a ton of stuff. You can split things like /usr/bin but it can get really messy, really fast.

Have you not seen a link to this post on your travels? You'll need a LiveCD or LiveUSB to action it, but it's very simple once you're at that point. Here are the main points:

• mount your windows partition (where the Wubi install sits)


• fsck the Wubi filesystem to make sure it's okay. If you don't do this and it has corruption in it before resizing, bad things can happen.


• resize2fs the Wubi filesystem to increase its size.


• Have a snack, chill out, high-five yourself... You've just increased the partition size.

Those aren't the full commands, I'll leave those in that thread because it seems to be well maintained.

Failing that, installing Ubuntu only takes a few minutes. If you like it, perhaps you should consider a proper install (disk performance is better too).

compiling - What's a simple way to recompile the kernel?

I'm interested in compiling a new kernel under Ubuntu 12.04 x86 64 bit.

I found this wiki page which is basically a mirror for this blog and there are a lot of steps (git, etc.) that appear useless to me.

With earlier releases/distros, I used to create a .config file and modify a Makefile if I needed to, then just run make and it's done.

Is there is a simple way to do this under Ubuntu?

1. Use apt-get source to download the Ubuntu version of the kernel

apt-get source linux-image-$(uname -r)

gives a folder that contains, for example:

linux-3.2.0                linux_3.2.0-26.41.dsc

linux_3.2.0-26.41.diff.gz  linux_3.2.0.orig.tar.gz

The bolded diff includes all the Ubuntu/Debian customizations.

2. To build a stock kernel with your own .config, use the "old-fashioned" Debian make-kpkg method

This is the alternate old-fashioned way described in the wiki:

sudo apt-get install kernel-package

If you are compiling a kernel for the first time:

sudo apt-get build-dep linux-image-$(uname -r)

Then cd into the source directory (here, linux-3.2.0), and either run make oldconfig to create .config file with your running kernel's configuration, or copy a third-part .config to this directory.

Depending on whether you want a text or graphical config, install:

(Text)

sudo apt-get install libncurses5 libncurses5-dev

(Graphical)

sudo apt-get install qt3-dev-tools libqt3-mt-dev

And then run:

(Text)

make menuconfig

(Graphical)

make xconfig

When done, just run:

fakeroot make-kpkg -j N --initrd --append-to-version=my-very-own-kernel kernel-image kernel-headers

where N is how many jobs to run in parallel (usually the number of CPUs you have), and my-very-own-kernel is a custom string to identify this build.

When done, the kernel image and header files will be ready as debs in the parent directory; you can install them with sudo dpkg -i, which will also take care of adding GRUB entries, etc.

How to replace old Ubuntu with new Ubuntu (Dual boot), not given option to "Replace"

I am dual booting Windows/Ubuntu. When I boot my new Ubuntu installation media I am not given the option to "Replace" the old version, jut either make a new partition or replace the whole disk. Is there a reason why I am not given the "Replace" old Ubuntu with the new version option?

(P.S. I currently have Kubuntu and it has stopped loading so want to replace it with a new version.)

Thank you

kubuntu - How to get the newest version of a package installed via apt-get?

Is there a way to install the latest release of a program other than building it from the source?

I know that the packages/applications in the ubuntu repositories are not always containing the most recent versions of programs to ensure best system stability. However, I would like to have a newer version of the program "Okular". They already released one last October but it is still not upgraded in the repositories.

Is there a way to get it with apt-get? Maybe adding some other "unstable" repositories or using a special parameter?

The official Ubuntu repositories are maintained by a group of human beings. Because they need time to check each application for updates and pack them for distribution, they tend to be generally behind the curve. Stability is slightly less important.

To get bleeding-edge versions, you can build them from source or download the package from their site (if they offer one, I see Okular doesn't), but there is a way that you can use apt for certain programs. Launchpad allows users to create their own apt repositories that packages can be downloaded from. Packages downloaded from these are likely to update much faster than the Canonical archives because the developer will update it themselves when they make it.

Unfortunately, although Okular is on Launchpad, it doesn't have this. https://launchpad.net/okular

You might be able to convince them to make one, but otherwise I think activating the pre-released packages, as Radu proposed, is your best option.

wireless - Clarification of the third-party software options during system installation

During installation, the user is presented with the following dialogue:

The 'Flash' and 'MP3' options are pretty self-explanatory, but what about the 'wireless hardware' and 'other media' options. What 'other media' is this referring to, and how is the installation of wireless hardware handled. Does Ubiquity attempt to recognise the computer's wireless device and install the appropriate drivers or does it just dump a 'proprietary wireless driver module' into the kernel and be done with it? How does it react if the computer has no wireless card?

The "Install this third-party software" checkbox does two things:

1. It installs ubuntu-restricted-addons much later on in the main install process. This currently includes gstreamer0.10-plugins-ugly, flashplugin-installer (Adobe Flash support), gstreamer0.10-plugins-bad, gstreamer0.10-ffmpeg, icedtea6-plugin (Java and the browser plugin for it), and gstreamer0.10-fluendo-mp3 (MP3 playback support).


2. It asks the Additional Drivers (jockey) program to enable any drivers that can be automatically installed. Currently this is limited to just the Broadcom wireless (binary) driver.

If the computer is not connected to the Internet, the install will complete successfully; however, the following will happen:

1. Your location will not be automatically determined on the 'Where are you?' page.


2. The set of locations you can look up by typing in the box on the 'Where are you?' page will be limited to just the cities that represent a timezone (Oslen database locations).


3. If you have checked the 'Download updates while installing' box, this step will be skipped.


4. If you have selected a language without full language support shipped on the CD, the language support packages will not be downloaded as part of the Ubuntu installation process.

How Do I Change a Forgotten User Password Without Booting?

I can't log in to my root user's account. I've looked for a solution, but all of them tell you to do it from the boot options.

The thing is that my laptop's screen has turned black and it doesn't work anymore, so I've connected another monitor to the laptop so I can work on my computer, but I won't be able to see the boot menu on my new monitor.

Is it possible to change my password without using the boot menu?

Thank you!

nvidia - Ubuntu 12.10. Can't add custom resolution

System: Ubuntu 12.10, nVidia Geforce GT240 (nvidia-current privative driver), LG display connected to VGA-0

The 1920x1080 resolution is not listed, I've added it in Windows but I'm having problems doing the same Ubuntu.

Step 1) Obtain modeline

$ cvt 1920 1080

Step 2) Create custom mode

$ xrandr --newmode "1080p"  172.80  1920 2040 2248 2576  1080 1081 1084 1118  -HSync +Vsync

Step 3) Add custom mode

$ xrandr --addmode VGA-0 "1080p"

And then I get this error:

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  29

The xrandr output is

Am I doing something wrong?

Ok, this worked for me.

1) Edit /etc/X11/xorg.conf

2) In the section "Monitor", change HorizSync and VertRefresh to the correct values (consult your monitor specifications in the user manual). This is important or you will likely get an "signal out of range/sync" error in your monitor (if you make this mistake press ctr+alt+f1 and edit xorg.conf from console).

Section "Monitor"


    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "CRT-0"
    HorizSync       30.0 - 83.0
    VertRefresh     56.0 - 75.0
    Option         "DPMS"
EndSection

3) In the section "Screen" add this line.

Option "ModeValidation" "AllowNonEdidModes, NoVirtualSizeCheck, NoMaxPClkCheck, NoWidthAlignmentCheck, NoExtendedGpuCapabilitiesCheck"

4) Restart the system.

5) xrandr --addmode still won't work but you will have more resolutions available. Check out my new xrandr output:

Installing Windows 10 in dual boot with Ubuntu

I have Ubuntu 16.04 running on my machine, but for some purposes I need to install Windows. I like Ubuntu, however, and I wanna use it as my prior OS. So what I want to find out how to do is - how to install Windows 10 in dual boot os whilist keeping my Ubuntu 16.04 and how to ensure that Ubuntu is the default boot option? Also, is it than possible to make them each get access to only part of my hard drive? I got only one hard drive and I want each of them to use seperate disk part and not overlap.

So how do I do this all?

How to upgrade or install Ubuntu 18.04 LTS from Ubuntu 16.04 LTS from ISO file without any USB or DVD?

I downloaded the latest LTS release of Ubuntu 18.04. I currently do not have any spare USB or CD/DVD. So, I just want to install or upgrade my current system from that ISO without making any bootable device. Is it possible? If yes, then please tell me the whole process!

updates - Packages are not available for installation

Changing some Software Update settings I possibly corrupted something, and now I don't see many packages in the list. For example:

alex@u120464:~$ sudo apt-get install codeblocks
[sudo] password for alex:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package codeblocks

I checked all options in the Software Sources dialog, but packages are still not available. How can I fix this?

OS: Ubuntu 12.04, 64 bit.

Additional information.

It looks like most Ubuntu repositories are not searched, how can I restore default update behaviour?

compiling - How to create package including source codes, which compile during installation

Is it possible to create a deb package for Ubuntu, which contains source codes and automatically compiles them into executable during its installation?

I haven't found any tutorials for this, only tutorials about "how to compile package from sources", which is quite different thing from what i want. That makes me think, this might not be a good idea.

So, is this possible at all, and if yes, is it a good idea?

That's not how .deb packages work. They contain pre-compiled software, you can't just make a deb package with source code. I have a suggestion: why don't you make a .tar.gz package containing your source code and a script to compile it? The script should look like this:

#!/bin/bash

# here comes the code to compile your source code, like the usual. Change to fit your needs.

./configure

make

make install

boot - How do I fix this problem with grub after installing Ubuntu server?

I've installed GRUB as part of the Installation process of Ubuntu Server 13.04 LTS edition.
This is the screen that I get after booting from my hard drive:

GRUB: Loading.
Welcome to GRUB!
error: file '/boot/grub/i386-pc/normal.mod' not found.
grub rescue>

I tried installing Ubuntu Server (after numerous installs) on my partitioned hard drive. I remember them as sda5 and sda6. The install was to dual boot with Windows 7.
When I first install grub, I used the i386 iso, but after I found out that I could use the amd version to optimize, I installed that.

Now, grub has an error and I don't know what to do.

Almost all the help tell me to use a CD-ROM, but I used a flash drive. Now, I just want to either repair grub, or get rid of Ubuntu and grub entirely, as long as I can save my Windows7 partitioned on my sda1-3.

I'm very new, so step by step instructions help.

Can I do a Silent or Unattended Release Upgrade?

How do I upgrade to a new Ubuntu version without having to react to prompts?

I'm on 12.04 now and would like to install 12.10. When I start the update, it usually downloads stuff, then asks a question, installs a bit, asks a question, etc.. I leave it overnight and sometimes find that it made almost no progress updating. I'd like to just kick of the process, go away and have it finished after a couple of hours. I'm fine with it automatically updating configuration files in /etc and so on. So how to start an unattended upgrade?

The following command upgrades to the new stable release without prompts:

do-release-upgrade -f DistUpgradeViewNonInteractive

The following command upgrades to the current development release without prompts:

do-release-upgrade -d -f DistUpgradeViewNonInteractive

I haven't tested it, but it seems it just performs the default action when a question arises. It also times out any scripts if they hang for too long.

You might have to do use dpkg-reconfigure afterwards if you are unhappy with the configuration of certain packages, but most of the time you should be ok.

nvidia - ubuntu 18.04 Black screen after login

In ubuntu 18.04 after discovering that the wrong nvidia driver was polluting my kernel.log I've tried different combination of nvidia drivers with no success.

When I sudo service gdm start the login screen shows up but after login a black page blocks everithing,

4.15.0-33-generic

How can i diagnose/solve this?

UPDATE:

Same problem with a fresh install after installing nvidia recomended drivers.
Resolved avoiding nvidia drivers.

Should this be a hardware error?

Btw video card runs with no problem in Windows.

I had same problem with both Ubuntu 18.10 and 19.04. I have a dell Vostro 3670 (see https://linux-hardware.org/?probe=0f87997cd1). This solution did not work for me. After reboot the screen stays blanc. I found a solution to restore the Ubuntu desktop at least. From #17 on proprietary drivers not showing up - Page 2

I found several proposed solutions for this issue to install the
Nvidia drivers. None of them work for me. I found 2 methods that
enable you to recover the Desktop environment when this happens:

First by Fossfreedom at -
https://discourse.ubuntubudgie.org/t/nvidia-390-black-screen/97/14

You have to do a safe boot and go to root, then:

sudo apt-get remove nvidia-*
sudo apt install nvidia-prime
sudo prime-select intel

Then reboot.

Second form sgian entry #3 at
https://ubuntuforums.org/showthread.php?t=2399985

Also do a safe boot and go to root. Then:

sudo apt purge nvidia*
sudo apt install --reinstall xorg xserver-xorg-core

Then reboot.

resolution - Why is there no 20" HP LCD information in Raring?

My HP S2031 is limited to 1024x768 max.

I have spent hours tracking this down.
I've installed a new driver and had to remove it because it broke Unity.
I read about the amdconfig command, which is not on my system.
I learned about the xrandr & cvt functions and attempted to use them with no change.
xrandr --newmode "1600x900R" 97.50 1600 1648 1680 1760 900 903 908 926 +hsync -vsync

Using grep I found the file /usr/share/hwdata/MonitorsDB,
and I have determined that my monitor is not on the list.
In fact, there are no 20" 1600x900 native resolution HP brand LCDs in the file!

Within the "Displays" application the monitor is listed as Unknown.
Is this the reason for the lack of proper graphics driver?
Why my monitor can only be set to display a distorted 1024x768 or 800x600?

Does anyone know the format of the data to add to this MonitorsDB file, and would it work?

My system's output from cvt -r 1600 900 (what I used) is shown above.
cvt 1600 900 yields:
# 1600x900 59.95 Hz (CVT 1.44M9) hsync: 55.99 kHz; pclk: 118.25 MHz
Modeline "1600x900_60.00" 118.25 1600 1696 1856 2112 900 903 908 934 -hsync +vsync

gtf 1600 900 60 yields:
# 1600x900 @ 60.00 Hz (GTF) hsync: 55.92 kHz; pclk: 119.00 MHz
Modeline "1600x900_60.00" 119.00 1600 1696 1864 2128 900 901 904 932 -HSync +Vsync

EDIT:

Users with less than 10 reputation can't answer their own question for 8 hours after asking. You can answer in 5 hours. Until then please use comments, or edit your question instead.

To fix no 1600x900 resolution for HP 20" monitor, I created /usr/local/bin/fix-resolution.sh containing these four lines
#!/bin/sh
xrandr --newmode "1600x900R" 97.50 1600 1648 1680 1760 900 903 908 926 +hsync -vsync
xrandr --addmode VGA-0 1600x900R
xrandr --output VGA-0 --mode 1600x900R
These xrandr changes will disappear on reboot, so I made the script executable and then created the file /etc/xdg/autostart/fix-resolution.desktop containing these 4 lines
[Desktop Entry]
Name=fix resolution
Exec=/usr/local/bin/fix-resolution.sh
NoDisplay=false
to automatically execute the script on startup.
The fix-resolution.sh script works when executed from the terminal after startup,
but does not automatically run during startup. I assume that this is not the proper place to ask a question about the startup sequence, I'm just letting you know what is needed to fix this problem in case anyone else has it too.

14.04 - No video signal for nvidia driver

I followed the steps in this answer entering these commands as I had a similar problem...

sudo apt-get install --reinstall ubuntu-desktop 
sudo apt-get install unity 
sudo apt-get purge nvidia* bumblebee* 
sudo apt-get install nvidia-prime 
sudo shutdown -r now

...but, after rebooting, I lose video signal during the boot sequence before the log in screen.

How can I get the video signal back? I have Ubuntu 14.04 and nvidia graphics card.

The sudo apt-get install nvidia-prime part of the linked answer installed an incompatible video driver.

I resolved this by:

1. booting into the advanced options from the grub menu,


2. selecting the first recovery mode option,


3. selecting the start networking option,



4. selecting the command prompt as root option

From the command prompt, I entered apt-get install nvidia-current
and installed compatible nvidia drivers.

This solution, or similar for different video cards, may help others with video driver problems.

boot - grub rescue prompt after installing grub into sdb

I installed Ubuntu Minimal 12.04 LTS from USB. Everything was OK. But, when I try to install Grub into /dev/sda, the installation stops with a "fatal error".

So, I just entered /dev/sdb (just tried), Grub got installed without any problem in /dev/sdb.

Then, the installation finished without any problem. But after restart, it says 'grub rescue'.

I had only 1 hard drive. So what is sdb? I thought, USB drive was sda, and my hard drive sdb. Is it possible?

How can I fix it?

upgrade an old "kinda" broken ubuntu from a working lubuntu

i've been searching for this but i couldnt find an answer. (to state that i did search)

is it possible to update my ubuntu 11.04 from my current Lubuntu 13.10 ?

i have and "old" pc. specs are:
cpu: amd athlon xp @1.9
vga: ati radeon 9200 agp 8x
ram: 1 gb module - 1 module for 256 mb total: 1,25gb
motherboard: a7v8x-mx se

a few years ago i installed ubuntu 10.04, put a lot of important files there, and kinda "never used it again", i just used ubuntu once or twice in a year, when searching for old stuff.
my ubuntu was working fine, but i couldnt upload videos to youtube anymore. firefox just freeze and chrome crashes.
so i uninstaled chrome and i couldnt install it back, because my version was not supported anymore. so i started upgrading (it was quite difficult because im a begginer)
and i managed to upgrade to 11.04.

when trying to upgrade to 11.10, linux wont let me log in, the clock on the login screen works, but i cant move the mouse, cant use the keyboard and cant enter a terminal (with alt + f2) i read that it wont load up my video card drivers or maybe its the mouse and keyboard.

entering text mode allows me to perform console commands such as "sudo upgrade" , but since the LIST file is "broken" and i have to replace some lines to the "old-repository" it wont upgrade anymore, it will never find the files required.

i tried to install 12.04 but the install fails (like its some hardware problem).
tired of reading, i find that the problem is my old video card, so i moved into a "light" version of linux and here i am, it works just fine, even faster i think.

im in Lubuntu 13.10 and i love it, but i CANT use the flash player, only a few sites allow me to use the flash, i try with chrome and cant even run the chrome browser.

so im ok with that, but, is it possible to update my ubuntu 11.04 from my current Lubuntu 13.10 ?

11.04 ubuntu has 65 gb in a 80 gb ide hdd
so im afraid that i might run out of space soon in this 15gb filesystem.

the files i had are OK, i can access all of them from here, i just cant use flash.

14.04 - Problem installing Wifi drivers dell

My PCI id is 14e4:4365

I am using trusty.

I tried to install drivers from this thread How do I install BCM43142 wireless drivers for Dell Vostro 3460/3560? and Broadcom 4365 wireless driver with 3.4 / 3.5 kernel Initially it was working well. After somedays I had to reboot everytime for installing wifi drivers. Recently I installed KDE and from that time it stopped working even after reboot.

My kernel version is 3.13.0-35-generic. Please help me I am struggling with this driver.
Also Is there some way I can change the driver to another say with different pci id.

Edit:
The answer was to remove b43 line from /etc/modules as Jeremy pointed out. Also I had some other conflicting driver which was to be removed.

With Trusty and the 3.13 kernel, it should be as simple as

sudo apt-get install bcmwl-kernel-source

And it might work without rebooting
http://packages.ubuntu.com/utopic/amd64/bcmwl-kernel-source/download

This updated version might fix it now

18.04 dual boot showing grub2 manual

Did a fresh install of 18.04 alongside Windows 10 (UEFI). Now my system boots only into grub2 commandline.

I am able to boot into both windows by executing

> chainloader (hd0,gpt1)/efi/Microsoft/bootmfgw.efi

and ubuntu by executing

> set prefix=(hd0,gpt6)/boot/grub

> set root=(hd0,gpt6)

> insmod linux

> insmod normal

> normal

I ran grub-install, boot repair several times after booting into ubuntu, but to no effect.
I still keep booting into grub commandline.

Any help is appreciated.

grub2 - How to re-insall libc6 after remove?

I removed libc6 manually (i.e. by sudo apt remove libc6 command) on my Ubuntu 18.04 system and after reboot, there is just grub command prompt:

GNU GRUB   version 2.02

Minimal BASH_like line editing is supported. For the first word TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.



grub>  _

Is there any way to reinstall libc6 and put my system working as before?

UPDATE1:

This is screenshot of my partition structure (as GParted shows):

/dev/sda2 is the partition that is encrypted and contains /etc/, /root/, /lib/, /run/ and other Linux OS default folders and was mounted (at my previous working Lubuntu) as / i.e. system root.

/dev/sda5 is the partition that is not encrypted and was mounted (at my previous working Lubuntu) as /home/ folder.

UPDATE2:

Although /dev/sda5/ is not an encrypted partition, but my /home/myusername/ folder is encrypted as follows and I do not remember how I did this encryption during OS installation and do not know how to recover my data in my /home/myusername/ folder:

lubuntu@lubuntu:~$ sudo ls /media/lubuntu/UUID/myusername/ -la

software installation - How do I install .run files?

My PC has both Ubuntu and Windows 7 installed. I have installed all my drivers in Windows like Nvidia graphics, motherboard etc. Shall I install them in Ubuntu too?

I looked on the web for my Nvidia drivers and I have found a .run file. How could I install it on my Ubuntu?

package management - Automation of installing programs from source

I occasionally face a problem when using programs for which developers don't publish deb packages and only provide source. Sometimes I find a PPA providing the package but sometimes I don't or sometimes I don't trust the third party's version of the package because the program is rather sensitive from the security point of view (e.g. a password manager).

I can install from the source but this is ok to do once, not to do it on regular basis so as to install program's updates. Therefore, I'm thinking...

Is there a tool which would automate installation from the sources?

1. Check for updated source. (e.g. in a Git repo)


2. Download the code.



3. Compile it in the background.


4. Offer installation the similar way the Ubuntu's update manager would?

I guess I could probably put the process together using Jenkins and some custom coding but it's possibly quite a bit of work and I don't want to re-invent the wheel.

PS: Answers like the one for Atom editor lack some expected features when having to deal with the installation of multiple programs this way:

• management of the configuration for each of them



• download from different sources (tar archive, Git repo, etc.)


• checking the source on daily basis and tracking whether there is a need to proceed with the update


• resolving dependencies


• check that the compilation succeeded


• offer to install the package instead of installing it automatically

In other words, I'm looking for something that would put user-friendliness into the process.

Linuxbrew

Linuxbrew is a fork of Homebrew, the macOS package manager, for
Linux.

It is exactly what you are looking for.

intel graphics - /etc/X11/xorg.conf doesn't exist?

Possible Duplicate:
Where is the X.org config file? How do I configure X there?

I'm trying to get my video card properly setup to handle 3D acceleration. After searching a bit, I've come across a few howtos that tell me I need to edit my xorg.conf file. That file doesn't exist. X.org is installed by default, I'm sure, and I figured this video card would be widely supported.

00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09)

Any ideas on how I can get this to work properly and play Starcraft II? Or any game for that matter? No resolution problems or anything, just no 3D rendering.

You COULD create your own xorg.conf by typing in a tty (not running gdm) the following:

X -configure

That will create a file called xorg.conf.new

To test the file type X -config xorg.conf.new

If you can load X and see the mouse and a good resolution then you can press CTRL+ALT+BACKSPACE to quit.

Copy then xorg.conf.new to the new location

cp xorg.conf.new /etc/X11/xorg.conf

Run startx to test.

Also the file does not exist since X.org does not needed anymore for some video cards (as i understand) only some Video cards have xorg.conf because of specific configurations (Like Nvidia and Ati). The rest of the X.org configuration options are in /usr/share/X11 like synaptics.

Now to test out if you have Direct Rendering do this:

glxinfo | grep -i "Direct Rendering" If it says YES then you can run several games. If it says NO then you might need more configuration. Also run glxgears to see how many FPS you have. If the glx commands are not there run sudo apt-get install mesa-utils

I can not guarantee that it will make it work for starcraft 2 (Remember you also need to have wine installed)

plymouth - What alternatives are available to replace the purple boot splash screen?

I would love an animated splash screen, just for a bit of eye candy to replace the purple splash (with 4 dots) during the boot sequence. I know it will slow down boot time but I don't care I just want it to look good. When I show my friends how much better looking Ubuntu is than windows the splash really lets it down.

Any one know a good alternative to the existing Plymouth boot?

I could not get mine to change the splash screen (with terminal or gui apps), and it is now broken, it just shows a load of error messages at boot but still starts Ubuntu.

Ubuntu Sunrise (plymouth)

I use an old favorite "Ubuntu Sunrise" in 12.04 (In fact I have been using it since 10.04 LTS). It's easy to install (instructions below) and it has never caused me any issues. However you should note that changing your Plymouth may cause resolution issues depending on your own resolution.

INSTALLATION INSTRUCTIONS

Step 1:

Download the Plymouth Sunrise deb file from here.

Step 2:

Open the Terminal (Ctrl-Alt-T) and type

gksudo nautilus

Step 3

• Copy ubuntu-sunrise folder to /lib/plymouth/themes


• Copy the file splash into /etc/initramfs-tools/conf.d (Optional, for better buffer)

Step 4:

Type in the terminal

sudo update-alternatives --install /lib/plymouth/themes/default.plymouth default.plymouth /lib/plymouth/themes/ubuntu-sunrise/ubuntu-sunrise.plymouth 200
sudo update-alternatives --config default.plymouth

Step 5:

Choose the number associated with ubuntu-sunrise in the options that pop up.

Step 6

Type in the terminal

sudo update-initramfs -u

Then

sudo reboot

That's it.

Note: Some people have issues installing other Plymouth themes (I've never had any) and I would strongly advise you to take a look at these issues here at Ask Ubuntu to familiarise yourself.

drivers - Ubuntu 16.04 only works when secondary monitor is connected

I have Ubuntu 16.04 on a Gigabyte Aero 14 laptop having Geforce GTX 1060 VGA. Using different nvidia drivers results in different behavior. For example, "nvidia-384" and "nvidia-387" don't detect the second monitor.

Currently, I have installed nvidia-390 (tried both .run file from nvidia website, and the package from ppa:graphics-drivers/ppa). It works when the external monitor is attached, but when I disconnect the monitor and reboot, ubuntu crashes after login.

Some notes:

• I have already tried Ubuntu 16.04 + Nvidia Driver = Blank screen


• Reinstalled drivers


• Tried both UEFI disabled and enabled


• Tried Unity and Gnome



• Nouveau driver, nvidia-367, nvidia-384, and nvidia-387 don't detect my second monitor


• Tried both mini-display to VGA port, and HDMI to HDMI


• sudo lshw -c video result: https://pastebin.com/raw/pZmkDbWC


• CPU Info: Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz


• BIOS info:


• In BIOS, the only option related to VGA I see is 3D Graphic Acceleration

I also checked the status of Network Manager:

kalayaan001@Kalayaan-MM061:~$ nm-applet
An instance of nm-applet is already running.
** (nm-applet:1727): WARNING **:   constructor(): Couldn't initialize the D-Bus manager.

How can we initialize the D-Bus manager?

kalayaan001@Kalayaan-MM061:~$ nm-tool
NetworkManager Tool
State: disconnected
- Device: eth0 -----------------------------------------------------------------
  Type:              Wired
  Driver:            b44
  State:             unavailable
  Default:           no
  HW Address:        00:19:B9:85:01:CA
  Capabilities:
    Carrier Detect:  yes
    Speed:           10 Mb/s
  Wired Properties
    Carrier:         off

It seems that all it can detect are the devices of wired Internet. How can we make it recognize the devices for wireless?

I then checked for blocks, but found none.

kalayaan001@Kalayaan-MM061:~$ rfkill list
0: dell-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: no

So, I thought it to be a driver problem and, surely enough, I found in "Additional Drivers" that it was lacking in a Broadcom® STA wireless driver. Unfortunately, getting the driver didn't fix it, either. It still cannot detect anything.

How is this fixed?

Thank you for your time.

Response to sagarchalise:

I installed all 4 entries under the keyword "bcm4311": firmware-b43-installer, bcmwl-kernel-source, broadcom-sta-common, and broadcom-sta-source. (There is even b43-fwcutter, though that appears for the broader keywork "bcm".) The problems is still there.

Additional Drivers reports: "This driver is activated and currently in use."

Here is ifconfig:

kalayaan001@Kalayaan-MM061:~$ ifconfig

Here is iwconfig:

kalayaan001@Kalayaan-MM061:~$ iwconfig
lo        no wireless extensions.
eth0      no wireless extensions.

How can I get these extensions?

The results of 2 codes seem to have changed in the process:

1) nm-tool

kalayaan001@Kalayaan-MM061:~$ nm-tool
NetworkManager Tool

Everything after "Tool" is gone.

2) sudo lshw -C network

In Ubuntu code, what does"UNCLAIMED" mean?

I tried the code suggested in the website. Unfortunately, there was no effect. I will try again in the morning (It's past bedtime in my timezone. So, I'm just about to retire to bed.)

Any more proposals?

Thanks again for your time. Your reply is most appreciated.

Take care,
