apt - What can I do if a repository/PPA does not have a Release file?

When updating, I get the following error message:

W: The repository 'http://ppa.launchpad.net/mc3man/trusty-media/ubuntu xenial Release' does not have a Release file.

Here, I find another statement on this error: How can I fix a 404 Error when using a PPA or updating my package lists?

This recommends removing certain PPAs; and, I'm not sure if I should do that since it might mean not getting the updates that I need.

Is this what I should do?

The PPA you've added does not support your version of Ubuntu. For example, the ppa:mc3man/trusty-media PPA is only for Trusty (Ubuntu 14.04) only (trusty-media). Obviously, it has no files for Xenial (16.04). You can check the PPA's Launchpad page to see which versions of Ubuntu are supported.

I'd suggest the following:

• Remove the PPA for older releases. For this example: sudo ppa-purge ppa:mc3man/trusty-media

  
  



• If there's a PPA for your version, add it. In this case, there's a PPA for Xenial: mc3man/xerus-media. You can add it using sudo add-apt-repository ppa:mc3man/xerus-media

partitioning - Partition a LVM disk

I have Ubuntu 14.04 installed.
I want to add partitions table to a LVM disk of 465 GB.

I would like to make two partitions without loosing any data. Gparted is showing that the whole 465 GB of the disk is used but I have over 150 GB left.

What am I missing?

unity - Disable new keyboard shortcut for Show Desktop

After a recent upgrade of 14.04, an icon "Show Desktop" appeared in my launcher bar.

I removed it with Unity Tweak Tool.

A new keyboard shortcut was also setup: Super+D now also shows the desktop. This is annoying, since pressing Super+Alt+D in that order is not the same as pressing Alt+Super+D in that order. The former is erroneously interpreted as Super+D on my machine.

What I would like to do in a first step is to disable Super+D, but I cannot find where I can turn this off.

Here are the things I checked:

• nothing in Settings > Keyboard


• there is something in CompizConfig Settings Manager > Unity > General, but it is set to d. Disabling it does not disable d.


• I disabled the shortcut in Unity Tweak Tool > Window Manager > Keyboard shortcuts > Show desktop


• gconf-editor -> apps/compiz-1/plugins/showdesktop, I can't find anything about keyboard shortcut there


• dconf-editor -> org/compiz/profiles/unity/plugins/unityshell -> show-desktop-key is Disabled

How do I disable the new d shortcut?

nvidia - Open Source friendly Graphics Card manufacturers?

Everyone knows that in general, Nvidia has the best supported graphics cards under Linux. But I don't want to buy into Nvidia's proprietary drivers if I don't have to. ATI has open source drivers, but they have almost no support, and their open source drivers are significantly worse than their closed source drivers. Intel has open source drivers, but their graphics are all integrated and built into the motherboard.

Are there any graphics card manufacturers which have open source drivers and are actually friendly with the open source community? I would gladly like to purchase from them if they exist.

dpkg - Package dependency problem (offline install of wireless drivers)

I have a friend wanting to install Ubuntu 10.10 as a dual-boot with Windows through Wubi. Unfortunately, he has a wireless card with a Broadcom chipset, and needs to install the drivers. There is no other way for him to connect to the internet; he cannot connect via Ethernet or another Wi-Fi dongle/card.

I generated a Synaptic download script for what I think are the appropriate packages, and he downloaded the .debs to \wifi\packages from Windows. He then ran these commands:

kieran@ubuntu:~$ cd /host/wifi
kieran@ubuntu:/host/wifi$ sudo dpkg -i packages/*.deb

The xz-utils package would not install separately either. Is there any way to solve the dependency problem, or an easier way to configure the wireless card?

From the line libstdc++6-4.4-dev depends on gcc-4.4-base (= 4.4.3-4ubuntu5); however:
Version of gcc-4.4-base on system is 4.4.4-14ubuntu5. I am 99% confident you are trying to install 10.04 (Lucid) packages on a 10.10 (Maverick) system.

This is almost always a bad idea.

I'm not sure about the details of your Synaptic download script but I hope you can use this information to modify the script to work.
