Printers Settings UI crashes, system printing service unavailable

  • 772

In Ubuntu 20.04 in the GUI settings, printers - I get the message 'Sorry! The system printing service doesn't seem to be available'.

I have a Canon MF643Cdw printer on wi-fi. CUPS seems to be working fine (no errors in systemctl). I can even print the test page from localhost:631 using either no driver or the canon UFR 2 driver,

system-config-printer-gnome 1.5.12-0ubuntu1.1 is installed.

I've tried this solution to no avail. I've also tried purging and installing cups again with apt.

The canon printer utility can't find the printer in it's network IP address either.

Interestingly, lpinfo -m says: Bad file descriptor

Any help/advice is appreciated.

    Add the name of the localhost cups server into /etc/cups/client.conf

    ServerName localhost:631

    Restart the cups service

    sudo systemctl restart cups

    The UI works now.
