[Bug 1563945] Re: package avahi-dnsconfd 0.6.32~rc+dfsg-1ubuntu2 failed to install/upgrade: subprocess installed pre-removal script returned error exit status 1

[Jeffry Johnston]

Ran into this problem today on 16.04. Here's a brute-force hack that got
me past the problem. Attempt at your own risk:

# First, try to update:
sudo apt-get upgrade
# STOP if you don't see the following messages:
# Job for avahi-daemon.socket canceled.
# dpkg: warning: subprocess old pre-removal script returned error exit status 1

# Here's the hack:
sudo sed -i.backup 's:deb-systemd-invoke stop avahi-daemon.socket >/dev/null:echo:' /var/lib/dpkg/info/avahi-dnsconfd.prerm

# Try to update again
sudo apt-get upgrade
# avahi-daemon should now install without the pre-removal script error message. If it doesn't, you should restore the backup:
sudo mv /var/lib/dpkg/info/avahi-dnsconfd.prerm.backup /var/lib/dpkg/info/avahi-dnsconfd.prerm

HTH
