I am almost certain that the lvm2 messages happen in the couple of minutes before the box crashes/reboots itself. The fact that they happen over several minutes is part of what makes me think that it's coincidental and just something that's unhappy because we're in the middle of installing stuff underneath it. But they were significant and they did happen at the right time, so I didn't want to leave them out.
I can try to get some time from someone here to set up a machine, remove just our custom edits, and try an upgrade if that seems valuable. I'd also appreciate any other suggestions for things to try -- I don't think we can try every possible combination but we can try at least a few things if anyone has any ideas. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1789977 Title: Upgrade from 16.04 to 18.04 crashed, required dpkg --configure -a to recover (multiple machines) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1789977/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
