It seems that CUPS is still masked and it seems that by force-removing and re-installing it one does not get it unmasked.
Did you execute the commands as I told you in comment #23? Note that I have derived this command sequence from: https://askubuntu.com/questions/804946/systemctl-how-to-unmask Please run these commands and after that the commands of comment #31 again. Please post the screen output of all the commands here. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/2083530 Title: gnome-control-center not able to add printer or make settings To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/2083530/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
