This may take some work to untangle. First, this looks highly unusual and may be some cause of problems: udev 8191016 8191016 0 100% /dev
Second, python2.7 and python3 are not interchangeable. (The Python developers would have done everyone a service if they had chosen to rename the language instead of changing a version number. It's probably too late now but I propose "Boa".) The programs that require python3 genuinely require python3, and the programs that require python2.7 genuinely require python2.7. Use the AptOrdering.txt file here or your terminal scrollback to figure out which packages to put back. It might take a lot of tries and re- tries to get them all put back. Good luck. ** Changed in: libgksu (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1541800 Title: package libgksu2-0 2.0.13~pre1-6ubuntu7 failed to install/upgrade: subprocess installed post-removal script returned error exit status 127 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libgksu/+bug/1541800/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
