[Bug 1841868] Re: Upgrade fails on systems with ubuntu-minimal package

[Chris Guiver]

Thank you for reporting this bug to Ubuntu.

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

See this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

Further there are many unofficial PPA's and no doubt unofficial
packages, which should be removed prior to upgrade
(https://help.ubuntu.com/community/CleanUpgrade).  These should be
removed as per the error message you should have received (with
suggestion to ppa-purge them).

Was your 18.10 system(s) fully upgraded before you attempted release-
upgrade?  If you'd like to remove the unofficial packages, and re-try
and still have the problem - you can return the Status of the bug back
to "New" when you comment the results of what you found. However given
that 18.10 is now EOL and unsupported, unless it impacts the 19.04 to
19.10 upgrade path it may be marked "Won't fix".

       Status: New => Incomplete

Title:
  Upgrade fails on systems with ubuntu-minimal package

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

Bug description:
  I installed Ubuntu originally with a server iso in order to have a
  custom LVM configuration, then I installed the `ubuntu-desktop`
  package. This is my laptop but I did the same thing on my desktop and
  encountered the same issue with this upgrade from Cosmic to Disco.
  That upgrade was rough. It got stuck so I did a force shutdown and
  several rounds of `sudo apt -f install`, `sudo apt dist-upgrade` and
  reboot.
