If you are hit by this issue, it seems sufficient to simply ask dpkg to finish configuration as it seems the prerm script isn't retried
$ dpkg --configure -a Or you can just re-run your upgrade command (e.g. "apt upgrade") which should do the same plus finish any upgrades that didn't finish (which may be the case) - you'll probably want to do that either way. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1760128 Title: package avahi-dnsconfd 0.6.32~rc+dfsg-1ubuntu2 failed to install/upgrade: subprocess new pre-removal script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/1760128/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
