I'am unable to purge the package due to an wrong .postrm script because I have uninstalled the linux-image-2.6.22-6-generic before purging the package linux-ubuntu-modules-2.6.22-6-generic.

I think postrm script needs to check if the correspondents linux-image-2.6.22-XXX are installed or not.

Proposed patch (or something like this):

I had the same behaviour for linux-ubuntu-modules-2.6.22-7-generic.

I can also replicate this behovior, the only way to purge ubuntu-modules is to reinstall the corresponding linux-image before removal. (or remove the postrm in /var/lib/dpkg but that's nasty).

Also, bug 138552 appears to be a duplicate of this: https://bugs.launchpad.net/ubuntu/+source/linux-ubuntu-modules-2.6.22/+bug/138552
