[Bug 1977493] Re: Upgrade from Ubuntu 21.10 to 22.04 fails - unmet dependencies: libpam-modules

[Frank Heimes]

To sum this up and to unblock:

The root cause of your issue is the use of pam_tally (and the non-
optimal way this situation is currently handled by do-release-upgrade),
like mentioned by vorlon (thx) in the previous comment(s) and also
indicated in the log you've provided.

Since either the pam_tally or the pam_tally2 module is in use by your system (in /etc/pam.d),
but pam_tally became obsolete and got meanwhile removed from PAM,
you must remove pam_tally before PAM can be properly upgraded.
(And notice that including these modules in your PAM configuration again after the upgrade will stop users from being able to log into the system.)
Consider pam_faillock as potential replacement for pam_tally.)

This needs to be manually done before running do-release-upgrade again.

  ---Problem Description---
  Upgrade from Ubuntu 21.10 to 22.4 fails

  I run do-release-upgrade and I got a message upgrade completed with
  errors. I rebooted the server and it is now in an undefined state
  between 21.10 and 22.04. Not all packages have been installed. I
  attach apt log and output of some commands:
