Title:
  Upgrade from 16.04.5 LTS to 18.04 fails on some items

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

Bug description:
  Did the apt-get update immediately before the offered upgrade to
  18.04.

  Went through smoothly until around 98%, when it stated that the update could not be completed and the system might be unstable. It would do some 'configure -a' (if memory serves right), and informed that it could not roll back. Then the upgrade process exited. Then - before manual reboot - I was offered two new updates: movieeditor and feh. I accepted, but stopped when it wanted to remove libcal3, systemd-shim and virtualbox. 
  Luckily, after reboot, it came up, but remains not upgradeable. It stops at an uninstallable systemd-shim. Any apt-get update doesn't help. 

  Observations throughout the upgrade process: 
  1. Early on, it had already popped up a message stating that systemd-shim could not be updated. Though then, I could continue, and did. 
  2. While doing the kernel update, it repeatedly warned 'no matching swap device is available'. I had/have no clue why, since I always had one, and have configured a partition as swap space.

  Actions: I had accepted at all questions of replacing / keeping conf-s
  with 'replace'.

  Now I'm looking forward to some help on completing the update, and
  removing the old packages (this also stops with systemd-shim).
