Bug Description

Binary package hint: cups

In cups 1.4.0-5 on Karmic x86-64, upgraded from Jaunty, I find that cups no longer starts. It exits with signal 15 after putting this in error_log:

X [13/Sep/2009:18:25:24 -0700] No valid Listen or Port lines were found in the configuration file!

After looking in /etc, I found that cupsd.conf is empty. I purged cups and reinstalled it, and now cupsd.conf has contents. I have never edited cupsd.conf. Therefore I think there's some kind of error in the upgrade procedure which leaves cupsd installed but not able to start.

Workaround is to purge and reinstall cups, or move cupsd.conf.default to cupsd.conf

The same happened on my computer too. It was a clean installation of karmic alpha 5 and then a full update to the current packages. CUPS worked right after installation, but stopped to work after update. The config file was empty. I could solve it by purging cups and installing it again.

Changed in cups (Ubuntu):
status: New → Confirmed

I copied a standard config file and it worked after that. It seems that particular update caused the conf file to become empty.

This worked for me:

dereck@yakisoba:~$ sudo cp /etc/cups/cupsd.conf.default /etc/cups/cupsd.conf
dereck@yakisoba:~$ sudo /etc/init.d/cups restart
