12.10 is very old and out of date - you'd need to upgrade at least 3 times in a row just to get to a version that's current enough to be supported. Instead, you should download a new CD image and install from that. It will get you to version 14.04 or 14.10 with a lot less downloading.

The specific answer that helped is this one. All I did was: sudo apt-get install xfdesktop4 and after a reboot, the icons and wallpaper appeared on my desktop. I hope this will be helpful for ...

I hit this exact problem doing an upgrade from 12.04 -> 14.04. I was unable to kill the frontend process as described above, because although I could launch an Xterm window, sudo and su segfaulted due to the system being half-upgraded. However, I recovered from the situation by rebooting, going into recovery mode, and getting it to fix broken packages. This ...

Update: Whether it was supposed to happen or not, it did; so I had to find a way to fix it. After lots of searching, waiting, and hoping for the best, I managed to recover my missing data!

If the upgrade fails, some information may be found in /var/log/dist-upgrade. To reproduce the errors visibly: Make a copy of /etc/apt/sources.list and edit the file replacing old repositories with new ones. Do sudo apt-get update sudo apt-get dist-upgrade -s This will do an upgrade dry run and print out any errors. Broken update-dependencies can be ...

I know it's been a while, however, I'd like to share what worked for me. It turns out that installing package 'cifs-utils' was all I needed to add. I had sec=ntlm, but still received an error stating wrong fs type, bad superblock. Installing cifs-utils fixed the issue and mount -a worked fine after that.

I'm having the exact same issue with an NVIDIA card (gtx770 and proprietary drivers) and the lowlatency kernel! I did not have the time to examine the problem here, but the result is the same so they may be related... I'm not able to access any other TTY, but using ssh I was able to conntect to the PC. I hope to find some time tomorrow.

You shouldn't need to save any files to properly upgrade. Upgrading only updates the software sources and packages to the latest version. Configuration files are generally not touched, or simply replaced by the new version. Only if you made changes to some configuration files yourself, you might want to make a backup in case it gets overwritten by the ...

Use a live OS USB and boot the OS then extract the files you need. Don't worry your files are most probably as they were. If its a problem with grub only then you might as well install boot-repair and repair it. Go here how-to-install-the-boot-repair-tool-in-an-ubuntu-live-disc to know how.

OK! Michael's comment was answer too, actually. And it is really useful... One of ways to do is just remove hard drive from that computer and connect it to other computer- than copy all files to that other computer. My future reccomendation: Use USB Flash to store your important files;)

In Ubuntu, at least in LTS releases, the upstream version numbers of many packages never change for a given release. There are very few exceptions, such as Firefox, and the kernel. You have three options: Upgrade a release. Not really an option. Find a PPA you can trust. Compile from source. This is definitely a viable option, but the exact steps depend ...

The standard Ubuntu NVidia drivers generate some problems on slightly older and slightly newer NVidia hardware. If you want more then the standard Ubuntu repository drivers, install the xorg.edgers PPA.

It could happen for multiple reason. One of them could be, your Ubuntu partitions space has all filled up. And that's why no other files could be downloaded. If this is the reason, Move some of your files to other place. Then resume or restart the upgrade process. Another reason could be that, Your Internet is disconnected for reasons such as reached Data ...

If you boot off the bootable CD/USB & select the 'Try Ubuntu' option you will have a working system; plug the USB drive in, it should mount; you should also have an icon for your main (corrupted) drive, which you can double-click & it, too should mount. Assuming it does, you can navigate to your files & copy them safely to the USB drive. If this ...

The LTS in 12.04 LTS is supposed to mean Long Term Support, so it should get important updates like security updates for a "Long Term" (currently 5 years). You should be safe keeping 12.04 and just updating it, no need to upgrade to 12.10 or a newer version. That said, the newer versions could offer newer features that 12.04 LTS may not have, like newer ...

Because they are different goals in terms of APT, apt dist-upgrade upgrades system by upgrading, installing and removing; apt-get upgrade upgrades by only upgrading packages, apt upgrade upgrades system by upgrading and installing packages.

It really shouldn't take this long. I assume something went wrong and it's unlikely that further waiting will be of any use. Most likely your system didn't survive the presumably failed release upgrade and only a new installation might be able to get a fully working system again. So the steps that seem apt now are these: Cancel the upgrade (If necessary ...

I'm not sure what APT::NeverMarkAuto really does, whether it stops it from being considered for dependency resolution. edit /etc/apt/preferences and put in: Package: mono Pin: version * Pin-Priority: -10 (warning, I didn't test this. Even if it does work, this might stop you from even installing it manually.) More docs in the apt_preferences(5) man ...

Some installer may prompt for separate boot partition, and if that is small size then it can become full and fail to build new kernel/initramfs. Check this with df?
