[Bug 1961432] Re: Upgrading from 21.10 to 22.04 fails to upgrade snap core18

[Nick Rosbrook]

Hi Lex,

I notice that the attached VarLogDistupgradeMainlog.txt file indicates:

2022-02-18 09:02:10,295 DEBUG refresh of snap core18 succeeded

I have been trying to reproduce the "Cannot upgrade core18" error
message, but have not had any luck. Can you provide any additional
information about the error message? Was this the exact wording?

  Upgrading from 21.10 to 22.04 fails to upgrade snap core18

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

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.
