Avahi-dnsconfd update bug and workaround


In case you are hit by https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/1760128 trying to upgrade avahi-dnsconfd in 16.04, there is now a workaround (comment #4 in the above link).

Sub-process /usr/bin/dpkg returned an error code (1)
Ubuntu MATE 18.04 Beta 2 is available now!

Thanks for this!

Encountered this while upgrading from 16.04 to 18.04, followed these instructions posted elsewhere:

sudo systemctl disable avahi-daemon
sudo apt update && sudo apt upgrade
sudo systemctl enable avahi-daemon


That was quite annoying as the “Software Updater” propose me each day to update “Ubuntu Base” and failed with this 15 Kb update…

Thanks a lot @maximuscore for the workaround, it worked like a charm.

  1. in terminal
    sudo systemctl disable avahi-daemon

  2. I used the “Software Updater” GUI (System/Administration/Software Updater) to update the Ubuntu Base, once it was done (No failure this time!)

  3. then in the terminal again
    sudo systemctl enable avahi-daemon

Done! Thank you so much!
