Discovered this was a system-wide problem, not specifically related to cups. Backup program was holding open a very high number if inotify watches and this was causing issues for other programs (including cups). Solution was to add a conf file in /etc/sysctl.d that set a higher value for fs.inotify.max_user_watches than the default (and then force a reload).
In my case, this seems to work: echo "fs.inotify.max_user_watches=131072" >> /etc/sysctl.d/999-local.conf sysctl -p /etc/sysctl.d/999-local.conf Note that this solution may cause other issues on systems with low memory. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1952164 Title: cups.path repeatedly goes into systemd failed state To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1952164/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
