I did the following:
till@till-x1carbon:~$ sudo -i [sudo] password for till: root@till-x1carbon:~# systemd-analyze set-log-level debug root@till-x1carbon:~# systemctl stop cups.service Warning: Stopping cups.service, but it can still be activated by: cups.path cups.socket root@till-x1carbon:~# sleep 4 root@till-x1carbon:~# touch /var/cache/cups/org.cups.cupsd root@till-x1carbon:~# sleep 4 root@till-x1carbon:~# sudo rm /var/cache/cups/org.cups.cupsd root@till-x1carbon:~# sleep 4 root@till-x1carbon:~# systemctl stop cups.service Job for cups.service canceled. root@till-x1carbon:~# systemd-analyze set-log-level info root@till-x1carbon:~# journalctl -b > /tmp/journal.txt root@till-x1carbon:~#
And as you see, I could reproduce the error ("Job for cups.service canceled.").
