[Bug 1964561] Re: package libpam-runtime 1.3.1-5ubuntu4.3 failed to install/upgrade: installed libpam-runtime package post-installation script subprocess returned error exit status 255

[Seth Arnold]

These lines from the logs look most relevant:

Unpacking libpam-runtime (1.3.1-5ubuntu4.3) over (1.3.1-5ubuntu4.1) ...
Setting up libpam-runtime (1.3.1-5ubuntu4.3) ...

dpkg: error processing package libpam-runtime (--configure):
 installed libpam-runtime package post-installation script subprocess returned error exit status 255

Is pam missing a versioned pre-depends? or is something not prepared to
handle a non-interactive update?

Amit you can probably make progress by running this in a terminal: sudo
apt install -f

Thanks
