the problem seems to be that the package libglapi-mesa is not installed or at least not in a proper way workaround is to install it first
sudo apt-get install libglapi-mesa and after that sudo apt-get install linux-generic-lts-trusty libgl1-mesa-glx-lts-trusty xserver-xorg-lts-trusty linux-image-generic-lts-trusty that "solution" work for me my guess is that there are some confusions with other point releases/meta packages but i did not real investigate it -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1340613 Title: HWE upgrade not working in 12.04 due to missing packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1340613/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
