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

I had installed gnome classic and also (to test it) the Mate desktop.
I like Gnome classic best so I uninstalled the Mate desktop.
And now this avari package is missing.
