[arch-general] no cups web/server with new version?

Hi, I followed the cups instructions when it upgraded recently: % pacman -Qs cups local/cups 2.0.0-2 The CUPS Printing System - daemon package local/cups-filters 1.0.61-2 OpenPrinting CUPS Filters local/cups-pdf 2.6.1-2 PDF printer for cups local/lib32-libcups 1.7.5-1 The CUPS Printing System - client libraries (32-bit) local/libcups 2.0.0-2 The CUPS Printing System - client libraries and headers I stopped and removed the old service, reloaded daemons, started and enabled new services (org.cups.cupsd.service and cups-browsed.service). However it seems I don't have the server working, since I can't get to localhost:631, and: % dmesg | 'grep' cups [ 10.006918] systemd[1]: Cannot add dependency job for unit cups.socket, ignoring: Unit cups.socket failed to load: No such file or directory. [ 10.006965] systemd[1]: Cannot add dependency job for unit cups.path, ignoring: Unit cups.path failed to load: No such file or directory. [ 1652.605967] systemd[1]: Cannot add dependency job for unit cups.socket, ignoring: Unit cups.socket failed to load: No such file or directory. % lpinfo -v lpinfo: Bad file descriptor The only configs in cups-files: % 'grep' '^[^#]' /etc/cups/cups-files.conf SystemGroup sys root lp AccessLog /var/log/cups/access_log ErrorLog /var/log/cups/error_log PageLog /var/log/cups/page_log I noticed a prior e-mail about this, with similar dmesg indications, but the OP indicated he solved his problems by using the appropriate services. Though I think I have the right services started and enabled... BTW, the web interface was working prior to the update. Any hints? Thanks, -- Javier.

cups.socket and cups.path are the old names (used before the upgrade). Disable everything cups related by removing the symlinks. A find command should help you weed out stuff from before the upgrade: find /etc/systemd/system/ -iname "*cups*" Then, try reenabling and starting cups again. (Three symlinks should be created.) systemctl enable org.cups.cupsd.service systemctl start org.cups.cupsd.service Here is my current (working) configuration: $ find /etc/systemd/system/ -iname "*cups*" /etc/systemd/system/sockets.target.wants/org.cups.cupsd.socket /etc/systemd/system/printer.target.wants/org.cups.cupsd.service /etc/systemd/system/multi-user.target.wants/org.cups.cupsd.path The note about the renamed service files is on the wiki [1]. --Kyle Terrien [1] https://wiki.archlinux.org/index.php/Cups#CUPS_daemon

Right. Removed already. Thanks.

Then, try reenabling and starting cups again. (Three symlinks should be created.)

systemctl enable org.cups.cupsd.service systemctl start org.cups.cupsd.service

Here is my current (working) configuration:

$ find /etc/systemd/system/ -iname "*cups*" /etc/systemd/system/sockets.target.wants/org.cups.cupsd.socket /etc/systemd/system/printer.target.wants/org.cups.cupsd.service /etc/systemd/system/multi-user.target.wants/org.cups.cupsd.path

The note about the renamed service files is on the wiki [1].

Yes, thanks, I just didn't pay attention to the socket and path old units. Just the cups.service.

After disabling the remaining cups.socket and cups.path, rebooting, stopping and disabling org.cups.cupsd.service, and starting and enabling it again, I now don't see the dmesg cups stuff, thanks: % dmesg | 'grep' cups % However I still don't get cups working (not on the web interface, neither lpinfo): % sudo find /etc/systemd/ -name '*cups*' /etc/systemd/system/multi-user.target.wants/org.cups.cupsd.path /etc/systemd/system/printer.target.wants/org.cups.cupsd.service /etc/systemd/system/sockets.target.wants/org.cups.cupsd.socket % lpinfo -v lpinfo: Bad file descriptor I noticed org.cups.cupsd.service just fails: % systemctl status org.cups.cupsd.service ● org.cups.cupsd.service - CUPS Scheduler Loaded: loaded (/usr/lib/systemd/system/org.cups.cupsd.service; enabled) Active: failed (Result: exit-code) since Tue 2014-11-04 21:24:58 CST; 8min ago Main PID: 7988 (code=exited, status=1/FAILURE) Nov 04 21:24:58 m1 systemd[1]: Started CUPS Scheduler.

if I run cupsd directly:

Which is even more weird to me. cups named packages installed:

Thanks,

Does /var/log/cups/error_log say anything? I suppose you could always revert to a stock configuration (using the .pacnews) if you have to. --Kyle Terrien

--Kyle Terrien

Hmm, will try. The only *.pacnew I got from the cups upgrade was cups-files.conf, and it's already merged. I'll download it from the web and see if that helps. Thanks, -- Javier.

Hi Javier, like you I also had the same problem you are experiencing. But after changing the LogLevel in /etc/cups/cupsd.conf to: LogLevel debug I saw what the real problem was in /var/log/cups/error_log: [05/Nov/2014:20:35:50 +0100] Group and SystemGroup cannot use the same groups. Next I changed SystemGroup in /etc/cups/cups-files.conf which was: SystemGroup sys root lp to: SystemGroup sys root In /etc/cups/cups-files.conf Groups is commented out so this will default to 'lp'. After changing this I was able to start the cupsd again. Hope this helps, -Lex

Thanks a lot Lex. That was it. Actually as SystemGroup also includes by default sys and root, I just left it commented out as the Group line is. Seems to be working back. It didn't occur to me to increase verbosity (neither I knew how to before). Sorry about that. Thanks, -- Javier.
