Cups Server error. There was an error during Cups operation: 'server-error-service-unavailable'.

Me too! Same symptoms. Additionally, I get the following audit report in /var/log/syslog every day, which I believe is related:

Jan 25 07:37:04 artoo kernel: [3141949.390618] audit(1201264624.231:82): type=1503 operation="inode_permission" requested_mask="rw" denied_mask="rw" name="/dev/tty" pid=7571 profile="/usr/sbin/cupsd"
Jan 25 07:37:04 artoo kernel: [3141949.417150] audit(1201264624.231:83): type=1503 operation="inode_permission" requested_mask="rw" denied_mask="rw" name="/dev/tty" pid=7574 profile="/usr/sbin/cupsd"

I have two desktop users (on on console, one on a VNC server virtual desktop) and both get the daily "CUPS SERVER ERROR There was an error during cups operation: 'server-error-service-unavailable'" popup error message, and that is presumably why I get the syslog message twice daily.

I have not tried messing with permissions of /dev/tty, although that seems to be the culprit. Or is this SELinux profile related?

I'm willing to help debug.

Me too, so it seems to be a common error.
Printing still works even with the error message.
Whatever we should try please tell us.

package hint: cupssys

<AOL>Me too!</AOL>
It only seems to show up in my primary user. No other effect noted.

At some point in the past three months this problem went away for me. I'm at cupsys version 1.3.2-1ubuntu7.5

More information... It only happens when I log in immediately. If I boot and go away, and log in some time after the boot process completes, it never happens. This is repeatable. Sounds like a init order issue.

7.10 is EOF..verfied the bug in new version or close

Hardy has reached end of life, and this package is not present in later releases. Closing all related bugs.
