[Bug 1916651] Re: asks about irc user home directory during upgrade

[Brian Murray]

I also tried reinstalling the package after having already installed it
per the test case.

bdmurray at clean-groovy-amd64:~$ sudo apt-get install --reinstall base-passwd

Title:
  asks about irc user home directory during upgrade

Status in base-passwd package in Ubuntu:
  Fix Released
Status in base-passwd source package in Hirsute:
  Fix Released
Status in base-passwd package in Debian:
  Fix Released

Bug description:
  [Test Case]
  1) On an Ubuntu 20.10 system edit your /etc/apt/sources.list file to have hirsute instead of groovy (this is the easiest way to verify the fix because the release upgrade process disables -proposed)
  2) Run apt-get update
  3) Execute 'sudo apt-get install base-passwd'

  With the version of base-passwd in the release component you'll
  receive a prompt about moving the 'irc' user's home directory from
  '/var/run/ircd' to '/run/ircd'.

  With the version of base-passwd from -proposed you will not receive a
  prompt and will instead see the following dpkg message:

  "Changing home-directory of irc from /var/run/ircd to /run/ircd"

  [Where Problems Could Occur]
  In the event that there is a logical error when checking for the irc user and its old home directory being /var/run/ircd a debconf prompt may not be presented when it really should be.

  [Original Description]
  Upgrading from groovy to hirsuite, base-passwd asks if the `irc` user's home directory should be moved from `/var/run/ircd` to `/run/ircd`.  Having no IRC server installed makes this very confusing, but appears harmless (https://askubuntu.com/questions/876975/user-irc-inside-of-default-ubuntu-16-04-server).  Possibly caused by https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=946884, but can this not prompt the user for a decision?
