There is a workaround for this bug, which I found at: https://neklaf.wordpress.com/2015/04/02/workaround-to-debian-gnulinux-upgrade/ where you manually disable avahi-daemon before the dpkg operation and reenable it afterwards:
1. sudo systemctl disable avahi-daemon 2. (upgrade/reinstall avahi-dnsconfd) 3. sudo systemctl enable avahi-daemon This worked for me on 16.04.4. -- 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
