Bug#788374: system-config-printer-udev: systemd service fails with "failed to connect to CUPS"

[Tomaž Šolc]

Package: system-config-printer-udev
Version: 1.4.6-1
Severity: normal

Dear Maintainer,

systemd service "configure-printer" fails on boot with the following messages
in the journal:

jun 10 19:37:26 orion udev-configure-printer[733]: add usb-005-002
jun 10 19:37:26 orion udev-configure-printer[733]: device devpath is /devices/pci0000:00/0000:00:1d.1/u
jun 10 19:37:26 orion udev-configure-printer[733]: MFG:HEWLETT-PACKARD MDL:DESKJET 940C SERN:MY18S6D186
jun 10 19:37:27 orion udev-configure-printer[733]: failed to connect to CUPS server; giving up

This causes systemd to mark the host status as "degraded":

$ systemctl --failed
  UNIT                                  LOAD   ACTIVE SUB    DESCRIPTION
● configure-printer at usb-005-002.service loaded failed failed Configure Plugged-In Printer

It looks like configure-printer gets started before CUPS. At least according to
this systemd output, cups.service only started 3 seconds after the error
message above:

$ systemctl status cups
● cups.service - CUPS Printing Service
   Loaded: loaded (/lib/systemd/system/cups.service; enabled)
   Active: active (running) since sre 2015-06-10 19:37:30 CEST; 1h 24min ago

Otherwise as far as I can see, CUPS is configured and working correctly on my
machine.

Best regards
Tomaz
