This problem hit me hard today. Problems like this definitely diminish the user trust in the Ubuntu upgrade process.
The solution was a painful manual rollback, using the output of "dpkg --get-selections" from before the upgrade (this old habit has saved me in more than one occasion). Getting my system back to an operational state required considerable effort. Please give this problem a high priority, as it's bound to affect a lot of people. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1345217 Title: nvidia-304-update (video driver) got uninstalled and is uninstallable after update to HWE-Stack5 (from Ubuntu LTS 12.04.4 to 12.04.5) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-304-updates/+bug/1345217/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
