Ha. So apparently you have two overlapping instructions in 
/etc/cups/cupsd.conf: 'Port 631' and 'Listen localhost:631'.

Can you try to remove the three last lines of the 
/etc/systemd/system/cups.socket.d/cupsd-listen.conf file and try to 
restart CUPS?

If that works, I'll see if I can address that in the Debian-specific 
patches.

Cheers,
OdyX
