Turned out that the culprit, despite a very long list of Broken packages in Apt.log, was this inconspicuous line in Main.log:
DEBUG Installing 'xserver-xorg-video-all' (Distro KeepInstalledPkgs rule) So while technically my issue with this is fixed I think some work needs to be done to provide better, more accurate output with regards to issues like this. Same problem can manifest for different users with different packages being problematic and the Apt.log list of Broken packages in my case actually included essential packages to my ubuntu-gnome-desktop bundle which would have ravaged my system had I blindly removed them. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1691924 Title: do-release-upgrade fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1691924/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
