Cups will not start most times

[kgeekworking]

I recently started having a problem where about 75% of the time cups will not start. The web interface (cups-browsed) starts fine, but not the main cups server process (cupsd).

Dmesg shows that it was killed, but there is no more information

$ dmesg | grep cups
[   36.509001] init: cups main process (1304) killed by HUP signal
[   36.509014] init: cups main process ended, respawning
[   38.324324] audit: type=1400 audit(1424799911.058:31): apparmor="STATUS" operation="profile_replace" profile="unconfined" name="/usr/sbin/cups-browsed" pid=1548 comm="apparmor_parser"

I check the running processes and confirm that cupsd is not running:

$ ps -A | grep cups
 1559 ?        00:00:00 cups-browsed

I can then launch cupsd manually from a command prompt and it will start and work fine without errors:

$ sudo cupsd
 
$ ps -A | grep cups
 1559 ?        00:00:00 cups-browsed
 3893 ?        00:00:00 cupsd

This happens most of the time, but not all of the time. My best guess is that it is some sort of timing issue with startup services, but I am not really sure where to look.

Actually, it's not show it was killed. It's showing it was killed and restarted - which is normal during boot. Mine shows exactly the same except for the apparmor message because I don't have it installed.

root@office:~# dmesg |grep cups
[   11.220182] init: cups main process (766) killed by HUP signal
[   11.220193] init: cups main process ended, respawning

It must be dying later or not restarting correctly.

So when you boot and it's not running, is there anything in cups logs?

You might just try removing cups from apparmor.

sudo aa-disable /usr/sbin/cupsd
