Some more info: I was asked if I want to keep the old /etc/mime.types or replace it with a new version, then the process crashed.
I ran "sudo dpkg --configure -a" hoping to resume the process, and got asked the same question again, so I'm guessing that's the cause of the release upgrader crash. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1375088 Title: kubuntu-devel-release-upgrade crashes with TypeError To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1375088/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
