[Bug 1761682] Re: package avahi-dnsconfd 0.6.32-1ubuntu1 failed to install/upgrade: sub-process pre-removal script returned error-code 1

The issue occurred for me when the latest set of updates were applied.
Just trying to remove avahi-dnsconfd give an error about the pre-removal
script failing. Here is the output from 'apt remove avahi-dnsconfd'
