I have seen this same bug. I saw an error relating to nvidia-glx while upgrading. I have also seen the same error message if I go to synaptic->Status->Not installed (residual config) and try to purge nvidia-glx there. The error I get is:
E: nvidia-glx: subprocess post-removal script returned error exit status 2 nvidia-glx does not seem to be able to uninstall itself properly. -- [gutsy] problem with nvidia-glx https://bugs.launchpad.net/bugs/144899 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
