very very unlikely. We are in the middle of an ESR release and thus the packaging typically itself isn't changing much. The code responsible for this wasn't touched for over year now. But we won't get new information on this what really did happen on your system. Only if it is reproducible we would see if and were something is maybe broken and not correctly working. > Well, I could also try to report this to apparmor No need for (in this special case), the problem that AppArmor isn't following symlinks here is a known fact and the AppArmor people did know this.

Well, the difficult and time consuming debugging work is more the exception than the normal way and happily the Debian package maintainers are mostly can do this more effective than the package users. On the other hand documentation is mostly lacking or out of time (and for maintainers probably some boring work :P ). AppArmor is a suite with a lot aspects and corner cases. And unfortunately some things are impossible with the current used version. I'm always happy if users are coming up with improvements for descriptions, readmes etc. Especially for the AppArmor. So I want to say, it's not always the complicated things that need to be done, with a POV on the classical users it's mostly a lack of information and how to organize them. I like the Debian wiki and so we have a page for Thunderbird there too and we can easily link this from the readme files. https://wiki.debian.org/Thunderbird If you are interested to do any improvements at any thing please feel free to do so. -- Regards Carsten Schoenert
