Cups suddenly fails - Mate 19.1 (SOLVED)

Larry78723 · Post by **Larry78723** » Thu Mar 07, 2019 7:56 am

I have tried to get a new printer (Xerox Phaser 3260) installed but can't. The printer is hard-wired to the router and has a static address. My laptop is connected via WiFi. When I try to print anything it doesn't. When I click Menu->Administration->Printers, I get a window that says....Printers - localhost. In that window is 2 buttons. One is "Start Service" and the other is "Connect". I cannot click on anything except the "Connect" button. When I click the "Connect" button it brings up another window called "Connect to CUPS server. That window has a box that says " /run/cups/cup.sock " and a button that says "Connect". This brings up another window called "CUPS server error". There was an error during the CUPS operation: 'failed to connect to server'. When I tried to use the "Printing Trouble Shooter", it says " CUPS Service Stopped " "The CUPS print spooler does not appear to be running. To correct this, choose System->Administration->Services from the main menu and look for the 'cups' service". Here are the things I've tried:

larry@larry-Satellite:~$ systemctl restart cups

Can anyone provide some guidance on how to fix this? Thanks in advance.

Does

journalctl

show anything more than what systemctl shows after restarting cupsd?

Please post

/lib/systemd/system/cups.service

See how you go on when

Restart=always

is replaced with

Restart=on-failure

and

Code: Select all

systemctl daemon-reload

Where would I find that?

BTW - systemctl daemon-reload didn't help

brian_p · Post by **brian_p** » Thu Mar 07, 2019 10:34 am

It's in /lib/systemd/system/cups.service.

brian_p · Post by **brian_p** » Thu Mar 07, 2019 10:41 am

In case I wasn't clear enough. Restart=on-failure replaces Restart=always in /lib/systemd/system/cups.service. The systemd service has to be restarted with the daemon-reload command because the file has changed.

Finally:

Code: Select all

systemctl restart cups

Did everything and rebooted. Still the same. It may be easier to just do a clean install.

CUPS has shipped with

Restart=on-failure

in cups.service since version 2.2.8. The reason is at

https://github.com/apple/cups/issues/5263

Brian, decided it will be easier to do a fresh install. If that fixes the problem I'll come back and mark this solved.

Thanks for taking the time to try and fix this.

Ok. Good luck. Thanks for letting us know.

On reflection, the journal has:

polkitd(authority=local)[782]: Unregistered Authentication Agent for unix-process:17092:4178130 (system bus name :1.177, object path /org

and this could be the issue. I'm unsure what is going on here, but policykit is involved.

Not to mislead future readers of this topic: after reading

https://stackoverflow.com/questions/255 ... tion-agent

and further reflection, I'll back away from seeing polkitd as a cause.

Brian, did a fresh install, now all OK.

Thanks again.

I found this. Dated March 2019. I have the exact same problem. This was marked as solved, but the only way the user could get it to work was to reinstall the whole OS. That doesn't sound like a reasonable solution for most people to me. A week or so back, the updater did a repository refresh. It failed "couldn't find..." etc.. About the same time I had a cups update. Now no printers work. The system sees no printers. I get messages cups isn't running, or isn't installed.

I followed all the suggestions here and none of them work.
I would really like to solve this current problem.
I am not going to reinstall the OS to do so.

cliffcoggin · Post by **cliffcoggin** » Fri Sep 13, 2019 1:38 pm

The short term solution is simple: revert to a backup from before the problem began. You do have a backup don't you?

kschrock · Post by **kschrock** » Sat Sep 14, 2019 10:11 pm

Backup of what? Mint? Cups? The entire hard drive?
An update caused this problem.
It should be easy to fix.

cliffcoggin · Post by **cliffcoggin** » Sun Sep 15, 2019 5:38 am

It is easy to fix temporarily. Linux Mint comes with Timeshift, a system restore application that lets you revert to an earlier version. Look for Timeshift in Administration and see if you have a snapshot from before the problem began and restore to it. That should get you going while you find a long term solution, preferably in a new topic rather than jumping on the back of a old one.

If you don't have a suitable snapshot or you didn't set up a schedule I can not help except to suggest re-installation of the OS.
