cups-pdf: error during the CUPS operation: 'client-error-document-format-not-supported'. in Ubuntu 10.04

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in cups-pdf.

Please execute the following command, as it will automatically gather debugging information, in a terminal:

apport-collect 580837

This will help us to find and resolve the problem. Bear in mind that you may need to install the python-launchpadlib package from the universe repository. Additionally, when prompted to give apport-collect permissions for Launchpad you will need to give it at least the ability to "Change Non-Private" data as it will be adding information to your bug report. Thanks in advance!

When reporting bugs in the future please use apport, either via the appropriate application's "Help -> Report a Problem" menu or using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Obs.: these options (button 'Print Self-Test Page' and the button 'Clean Print Heads') are disabled in Ubuntu 8.04.

A solution to this problem could be disable these two buttons ('Print Self-Test Page' and the button 'Clean Print Heads') to the PDF printer: it has no sense keep them enabled in a "PDF printer".

I have found a solution executing these commands:

sudo chmod 700 /usr/lib/cups/backend/cups-pdf
sudo chmod 700 /usr/lib/cups/backend

and then I have deleted and reinstalled the PDF printer; now the PDF printer works fine.
Thanks for the attention.

The back-end itself is already chmod'ed to 0700 by postinst and thus requires no fixing.

Instead, the real issue seems to be that CUPS needs to ship /usr/lib/cups/backend that also has 0700.

The question is the driver. When I set it to 'Generic PostScript Printer', it works fine, too.

2.5.0-15 has a safeguard that fixes the directory's permissions as well. This really should be fixed by CUPS' maintainer scrpits, but it's a nice safeguard to have in CUPS-PDF too. The debdiff is minimal, since it's still 2.5.0, so I recommend simply pushing 2.5.0-15 as an update for Karmic and Lucid.

The package cups-pdf ver 2.5.0-15 came as an update for Maverick on June 11.

The changing of /usr/lib/cups/backend permissions here cause hanging of print jobs in the job queue which is resolved by resetting the permissions of /usr/lib/cups/backend back to 755.

See: https://bugs.launchpad.net/ubuntu/+source/cups-pdf/+bug/594364

It turns out that changing the backend directory's permissions to 0700 disturbs the operation of other CUPS backends.
Therefore, this change was reverted in CUPS-PDF 2.5.0-16.
