installation - Upgrade error due to another package management application running

Possible Duplicate:
Unable to use package manager due to “exclusive lock” error

I use Ubuntu 11.10 on my desktop PC. My update manager shows me the upgrade link to 12.04 LTS but when I click on it, and follow the instructions, my installation halts at the small 'Distribution Upgrade' window that shows the steps that the installation takes to install the new package (e.g 'preparing to upgrade' and 'setting new software channels' etc). Not even a second after the 'distribution upgrade' window appears, a error message saying 'Unable to get exclusive lock' appears with the message:

This usually means that another package management application (like apt-get or aptitude) already running. Please close that application first.

I then clicked cancel and went back to the update manager to try again. There I unchecked all the updates and then clicked on the 'upgrade' to 12.04 button and the same thing happens again. I tried with different user accounts but still no change.

This is not the first time I used to install Ubuntu via update manager. I first installed Ubuntu 10.10 from the live CD and then when Ubuntu 11.04 and 11.10 came out I installed them via update manager with no problem.

Please help me solve this.

firefox - Is there a workaround to view Adobe Access (DRM) flash videos on any browser?

Ubuntu 13.04
Google Chrome   31.0.1650.57 (Official Build 235101) 
OS  Linux 
JavaScript  V8 3.21.18.7
Flash   11.9.900.152

When I try to watch xfinitytv shows via streaming (specifically homeland - showtime) I get stuck at the 0:00 and it says buffering...

Some problems:

• These streaming services now require flash versions 11.8 or higher.


• Adobe flash in browsers other than Chrome (ex. firefox) are only supported up to version 11.2. So this won't work.


• Google chromes uses Pepper flash which is supported up to 11.9!, but "Viewing Adobe Access (DRM) content is not supported, since Adobe does not support it on Linux." (docs)

So it looks like I am screwed. I need version 11.8 or higher which means firefox is out the door since adobe only supports it up to 11.2. Chrome's pepper flash is currently at version 11.9, but since it is a Adobe Access (DRM content) it is unsupported for linux users.

Any ideas? I have hit a wall. VM (WINE) the only option? Can I somehow get pepper flash into firefox?

14.04 - How to install Ubuntu on External USB pen-drive

I want to install Ubuntu 14.04 on my USB Stick from which I can boot my computer and do some light c++, Java,Python programming. I don't need much space for storage. I have a Kingston 16 GB pen-drive. I used this as startup disk creator once but it was extremely slow. I also want to use this USB as live CD to install Ubuntu on any computer.

How Can I install Ubuntu 14.04 on my external USB Pen-Drive?

Even if you do decide to follow these instructions, I suggest you read the LiveUsbPendrivePersistent wiki page. Reading Wiki pages is a great way to learn and you'll know more about what you're doing - rather than just following steps blindly.

---

Normally, I'd suggest that you use the Startup Disk Creator in Ubuntu to do this - it has a really simple option:

that allows you to add MB of space to keep stored in reserved extra space. However, there is sometimes a bug with installing the bootloader:

at least for me. You also mentioned that you'd had issues with Startup Disk Creator created USB drives being so.

So, I'd suggest you use Unetbootin. It's not quite as polished, but it does the exact same job and has the exact same store in reserve functionality. It's what I use when creating LiveUSBs and has yet to fail me.

It's in the default repositories, so you can install it via sudo apt-get update && sudo apt-get install unetbootin.

Once it's installed, open up the dash (Super key - aka Windows key) and open up unetbootin - you'll have to search for it. It'll require the sudo password, just a heads up. You'd need sudo access just to install the app, so that's no problem.

Once unetbootin starts, you'll want to change the radio button from selecting Distribution (default choice) to selecting Diskimage and then click the ... button. You can then select the ISO and it will show up in the text box.

Once you've selected the ISO you want, make sure the type is set to USB drive and that it's targeting the correct USB drive. If you've got USB backup media or other USB sticks attached to your computer, you may want to consider disconnecting them for a bit - just to be safe and sure you don't accidentally overwrite some important data.

Now, to add the persistence of data, simply change the Space used to preserve files across reboots (Ubuntu only) value. This should create a file-system on the USB stick, along with the ISO contents, that will store your information across reboots!

Note, that if you use Unetbootin to create the LiveUSB, you'll have to specify the space in MB (MegaBytes) not GB (Gigabytes). A simple way to convert this is just punch into a calculator numberOfGigabytes * 1024. That will provide you with the correct amount of space in MB terms (as there are 1024 MB in a GB.)

Motion Computing LE1600 touchscreen functions unavailable in 14.04

I recently obtained a Motion Computing LE1600 that I replaced Windows XP with Ubuntu 14.04 on today, and I can not seem to get the touchscreen functions to work properly. Is there anything that can be done to rectify this issue?

installation - Ubuntu installer not seeing free space on hard disk (dual boot)

I'm trying to install Ubuntu (12.10) on a laptop on a 240 GB Intel SSD drive already containing a Windows 7 installation. I have the disk partitioned as follows:

1. 1500 MB, NTFS, system partition, something that the laptop came with


2. 198 GB, NTFS, Windows installation partition

These partitions are followed by 23 GB of free space.

The Ubuntu installer, however, is not seeing the free space. Instead what I get in the Installation type dialog, is the following:

I've already tried creating an unformatted primary partition in the free space (using Windows, obviously) but doing that didn't change the situation in any way.

Should I alter the partitions in some way in order to make the free space accessible to the Ubuntu installer or am I missing something else here?

Where did my Nvidia optimus card go?

I have an Asus UX32VD that has a Nvidia 620M card along with the integrated Intel graphics. I had Ubuntu 13.04 and I could use the Nvidia card with bumblebee for some time, then I it stopped working after a kernel or drivers update(don't remember) and I was busy and lazy to fix it and I didn't really missed using the card.

Then I found there is a partial support from Nvidia for the Optimus technology but it required newer packages versions, I also checked the nvidia-prime package in saucy-salamander made the setup completely painless so I said, What the.. lets upgrade to 13.10 to test the new feature.

I purged bumblebee and everything related to Nvidia and once I had my saucy install working I reinstalled the Nvidia drivers followed by the nvidia-prime package. Now I restart and ... surprise!(actually not a surprise,something like this always happens) no UI, a low graphics mode message and there I am.

Of course I didn't check before the installation with lspci if I had an optimus capable PC because I HAVE AN OPTIMUS CAPABLE PC but doing lspci or checking in dmeseg output I don't see any trace of the nvidia word, my card just disapeared.

Now I don't know how to fix it or what could be the cause. I can only think of two options, a fairy opened my pc and stole the Nvidia chipset while I was sleeping or in the bumblebee time my card got disabled(bbswitch?) and now the system doesn't detect it.
