Title:
  Upgrading from 21.10 to 22.04 fails to upgrade snap core18

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

Bug description:
  While upgrading from 21.10 (Impish) to 22.04 (Jammy) an error message
  pops up:

  Cannot upgrade core18

  When upgrade is complete the "snap list" command produces the output
  which includes the following old packages:

  core18
  gnome-3-28-1804
  gnome-3-34-1804

  I had to manually remove these packages in the order listed using
  "snap remove --purge <pkg_name>" command.
