Public bug reported: Trying to upgrade an Ubuntu 20.04 VM to Ubuntu 22.04.
Because of an old small boot partition, I had to make space and grow /boot so that do-release-upgrade would proceed. Unfortunately, it later aborted with (what I was able to copy): -------------------------------------------------------------------------------------------------------- missing systemd/system/multi-user.target.wants/ondemand.service deleted systemd/system/multi-user.target.wants/ondemand.service added systemd/system/systemd-resolved.service.wants/resolvconf-pull-resolved.service added systemd/system/timers.target.wants/dpkg-db-backup.timer modified udev/udev.conf modified update-motd.d/91-release-upgrade modified vim/vimrc.tiny Committed revision 454.
