Ubuntu 18.10 (cosmic) reached end-of-life on July 18, 2019.

Both releases are now EOL. Further to comment #3 I'm setting this bug to
"Incomplete".
If this is still when upgrading from/to currently maintained releases of
Ubuntu then please let us know otherwise this bug report can be left to
expire in approximately 60 days time.
