[Bug 1986705] Re: package base-files 12ubuntu4.1 failed to install/upgrade: subprocess installed pre-removal script returned error exit status 1

[Steve Langasek]

This does not look like an Ubuntu bug.  You have the most recent jammy
version of dpkg installed on your system according to your bug report,
however the upgrade failure shows an internal error when trying to
invoke 'dpkg --valiate-version' from dpkg-maintscript-helper.

What does `which dpkg` return on your system?

** Package changed: base-files (Ubuntu) => dpkg (Ubuntu)

** Changed in: dpkg (Ubuntu)
       Status: New => Incomplete
