I have the same problems as described in this bug. Every time I print something cupsd crashes with core dump and cups-browsed also crashes. My printer is a Samsung CLX 6260 Series. I can successfully print one job, then get the crash, then have to wait some minutes before the services are up again, and so on.
I found out that if I stop the cups-browsed service the problem goes away. This is fine for me as I've already added my printer manually and I don't need to automatically find new printers. For some odd reason, another copy of my printer is added even though the service was disabled. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1826648 Title: cupds crashes with core dump Status in cups package in Ubuntu: Expired Bug description: At home my cupsd daemon crashes all the time. Sometimes I'm able to print a few pages but in most cases it ends-up restarting and sending tons of crap to my printer resulting in multiple wasted pages with non-sense characters printed on it. I ended-up manually creating a core dump by launching it from root with: # cupsd -f -c /etc/cups/cupsd.conf (will attach core in post) I tried using the default drivers for my printer then using the Samsung provided ones with same result. My printer is a Samsung C460W. Here is the systemd status: $ sudo systemctl status cups ● cups.service - CUPS Scheduler Loaded: loaded (/lib/systemd/system/cups.service; enabled; vendor preset: enabled) Active: failed (Result: core-dump) since Sat 2019-04-27 09:49:09 EDT; 12min ago Docs: man:cupsd(8) Process: 15292 ExecStart=/usr/sbin/cupsd -l (code=dumped, signal=ABRT) Main PID: 15292 (code=dumped, signal=ABRT) avr 27 09:49:01 eclipse systemd[1]: Started CUPS Scheduler. avr 27 09:49:02 eclipse cupsd[15292]: free(): invalid pointer avr 27 09:49:02 eclipse systemd[1]: cups.service: Main process exited, code=dumped, status=6/ABRT avr 27 09:49:09 eclipse systemd[1]: cups.service: Failed with result 'core-dump'. avr 27 09:49:09 eclipse systemd[1]: Stopped CUPS Scheduler. I wasn't able to find the core dump it refers to so that's why I ended-up generating one by invoking cupsd manually then launching ubuntu-bug against the cups package.
