Comment 37 for bug 1642966

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.").

journal.txt attached.
