Having trouble reinstalling apache.

First go back to a state there all dependencies are satisfied:

 sudo apt-get install -f

Try to remove all apache stuff:

 sudo dpkg --purge --force-depends "apache*"

Reinstall now all necessary dependencies:

 sudo apt-get install -f

Now you can give the apache installation a new try. If the problem persists, please provide more informations.
