Comment 12 for bug 336558

Also happening in karmic (unattended-upgrades 0.52ubuntu1).
Any package with conffiles is not upgraded (incorrectly blacklisted even when none of the conffiles have been modified)

This is farily serious from a system admin perspective where we have custom packages to apply a standard configuration to a large number of systems, but we don't want to wipe customized configuration. Right now none of the updates will apply automatically.

Can I use the hardy backport on karmic? If not, can I get something that I can install on karmic to fix this? I can't wait for official fix to hit karmic-updates.
