There are at least two possibilities to deinstall software without all the dependency stuff.
The first one is :
dpkg -P --force-depends <PACKAGENAME>
This means the Debian Package Manager turns errors, based on dependencies, into warnings, and will deinstall the package. And by the way, with -P option, it will purge (remove) the config-files of the selected package.
The second one I know is:
apt-get remove --force-yes <PACKAGENAME>
This order causes apt-get to deinstall the selected package without paing attention to any troubles or dependencies.
But please be careful with this options! The result may be an unstable system!
-> So check the dependencies carefully and do not deinstall software other packages you need depend on.
Hope this helps you ...
