[Bug 1871960] Re: package libpam-modules 1.1.8-3.6ubuntu2.18.04.1 failed to install/upgrade: pre-dependency problem - not installing libpam-modules:amd64

Sun Apr 19 08:14:25 UTC 2020

I also experienced this bug. I was running Ubuntu 18.04, and I upgraded
to Ubuntu 20.20 yesterday by running `update-manager -d` on the command-
line, which launched the GUI. During the upgrade itself, I was shown a
dialog displaying an error relating to pam.

I've attached apt-term.log (for me) to this comment. Here is the
relevant error, I think, I don't know how to find the core dump:
