Comment 5 for bug 878734

It seems like the attached logs don't tell us why the post-install script returned an error.

This error might occur if you manually remove the "minidlna" user or "minidlna" group while having minidlna installed on your system.

There could be other problems that cause an exit status 2.

Since this bug is more than 3 years old, you probably can't reproduce this to figure out what's wrong. I'm marking this as "Incomplete". If anyone still has the same issue, I think you can run this to get more info about the error and post that as a comment:

sh -x /var/lib/dpkg/info/minidlna.postinst configure
