[Christian Ehrhardt  (paelzer)]

Thank you for taking the time to report this bug and helping to make Ubuntu better.

On upgrading a service this service has to be restarted to pick up the fixes.
Rather rarely a real issue occurs that the newer version does e.g. fail with the formerly working configuration.
But most of the time what happens is, that a service was installed, but stays unconfigured or experimented with but left in a broken state.

Your apache is broken by someone or some script deleting all the conffiles.
modified.conffile..etc.apache2.apache2.conf: [deleted]
modified.conffile..etc.apache2.conf-available.charset.conf: [deleted]
[...]
This will break the service.

Now on any update of the related packages that service has to be restarted, but since its config is incomplete/faulty it fails to restart.
Therefore the update of that package has to consider itself incomplete.

Depending on your particular case there are two solutions:
- either remove the offending package if you don't want to continue using it.
- Or if you do want to keep it please fix the configuration so that re-starting the service will work.

Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I'm marking this bug as Incomplete.

If indeed this is a local configuration problem, you can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

Or if you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New.
