I kept poking around and found a dpkg process running but doing nothing except spawning many grub-pc related processes. I killed all that, ran sudo upgrade-grub-from-legacy, then I was able to finish the upgrade.
I believe the root of this problem was with the grub-pc package, https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/654651 -- upgrade kubuntu 10.04 to 10.10 failed https://bugs.launchpad.net/bugs/654705 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
