[Bug 1990308] Re: Upgrade to 22.04 LTS failed part-way through, broke the system

[achan]

I'll leave my system running without rebooting for as long as possible,
in case it would be useful to collect more data.  If there are other
things I should re-install other than ubuntu-desktop, please let me
know.

Title:
  Upgrade to 22.04 LTS failed part-way through, broke the system

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  Attempted LTS upgrade from 20.04 to 22.04 using the graphical Software
  Updater.  Clicked ok to perform upgrade, made a choice about a config
  file /etc/systemd/journald.conf, then walked away to do something
  else.

  When I came back the system was still running.  But icons were missing
  from the task bar, and the activities launcher showed a lot of
  important built-in system applications were missing -- system
  settings, the file browser, etc.  The gnome terminal was gone, but I
  managed to open xterm.  `uptime` says the system didn't reboot.

  Looks similar to https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1969786
  I was able to recover to a partially usable system via `sudo apt install ubuntu-desktop` as mentioned in that issue's comments, but trying to launch the Software Updater causes it to crash.  Other faults may be present -- I haven't experimented much or rebooted yet.

  `apport-bug` was run after installing ubuntu-desktop
