Title:
cups-browsed fails to exit when systemd tries to shut it down
(SIGTERM)
Status in cups-filters package in Ubuntu:
New
Bug description:
The cups-browsed service fails to exit when systemd tries to stop it,
seemingly because /usr/sbin/cups-browsed fails to exit when it's sent
a SIGTERM signal.
Here are all the relevant logs in journald when trying to stop cups-
browsed using `sudo systemctl stop cups-browsed`:
Sep 11 10:17:26 ubun sudo[3370]: pam_unix(sudo:auth): Couldn't open
/etc/securetty: No such file or directory
Sep 11 10:17:26 ubun sudo[3370]: martin : TTY=pts/2 ; PWD=/home/martin ;
USER=root ; COMMAND=/usr/bin/systemctl stop cups-browsed
Sep 11 10:17:26 ubun sudo[3370]: pam_unix(sudo:session): session opened for
user root by (uid=0)
Sep 11 10:17:26 ubun systemd[1]: Stopping Make remote CUPS printers available
locally...
Sep 11 10:18:56 ubun systemd[1]: cups-browsed.service: State 'stop-sigterm'
timed out. Killing.
Sep 11 10:18:56 ubun systemd[1]: cups-browsed.service: Killing process 1471
(cups-browsed) with signal SIGKILL.
Sep 11 10:18:56 ubun systemd[1]: cups-browsed.service: Killing process 1521
(gdbus) with signal SIGKILL.
Sep 11 10:18:56 ubun systemd[1]: cups-browsed.service: Main process exited,
code=killed, status=9/KILL
Sep 11 10:18:56 ubun systemd[1]: cups-browsed.service: Failed with result
'timeout'.
Sep 11 10:18:56 ubun systemd[1]: Stopped Make remote CUPS printers available
locally.
Sep 11 10:18:56 ubun sudo[3370]: pam_unix(sudo:session): session closed for
user root
As you can see, I run the command at 10:17:26, then nothing happens
for 90 seconds, until systemd gives up and sents a SIGKILL at
10:18:56.
This problem hangs shutdown for 90 seconds, so it quite badly affects the
user experience of Ubuntu as a whole, even for users who never use cups.
