Seen the same on both computers that I upgraded to kubuntu vivid from utopic.
The first time it happened the upgrade was unattended. I left the machine running over night, so when found it stuck in the morning I basically thought that I might have stumbled in some glitch. But now I am seeing this for the second time in a row. In my case, it happened during the mime-config phase. The log are exactly as reported a python error with "TypeError: connect() slot argument should be a callable or a signal, not NoneType". The fact that kubuntu utopic is going EOL in less than a month is making me quite scared. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1448380 Title: 15.04 installer hung in configure step with exception in DistUpgradeViewKDE.py To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1448380/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
