Same bug in my case, but different solution. The bug appeared when I used "su root" in a terminal, then tried the upgrade using apt-get, synaptic, or dpkg.
However, when I used "sudo dpkg" etc from a user terminal, the installation finished correctly. I didn't need to make any changes to /var/lib/gdm. -- package gdm 2.28.0-0ubuntu8 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 https://bugs.launchpad.net/bugs/438789 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
