[Bug 1922401] Re: do-release-upgrade fails because it marks e2fsprogs for removal

[Jamie Flournoy]

I found the problem. Documenting here for posterity.

I had a file in /etc/apt/preferences.d/ containing this:

Package: *                                                                                                                   
Pin: Release v=18.04, -l=Ubuntu                                                                                              
Pin-Priority: 10 

I had added this a while ago to upgrade smartmontools to the version
from Bionic, but forgot about it. Removing this (commenting out these 3
lines) made the do-release-upgrade succeed.

Title:
  do-release-upgrade fails because it marks e2fsprogs for removal

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

Bug description:
  Here's the error that I think describes the problem in /var/log/dist-
  upgrade/main.log :

  2021-04-02 21:21:20,082 DEBUG The package 'e2fsprogs' is marked for removal but it's an ESSENTIAL package
  2021-04-02 21:21:20,129 ERROR Dist-upgrade failed: 'The essential package 'e2fsprogs' is marked for removal.'

  I've already removed all PPAs, purged uninstalled packages, fixed
  broken packages, and done "apt upgrade" and "apt dist-upgrade".

  My guess is that I installed somethingorother that is preventing the
  upgrade, but I've disabled all non-ubuntu sources from
  /etc/apt/sources.list, so I'm not sure why this is happening.
