As debian didn’t have the most recent version of a project im using and they took ages to add it, i wanted to install the new version, but debian stopped me and told me that other packages are depending on this. (Well it was a compiler and those packages where sourcecode packs and it was a point release… so who cares…)

There is an option in linux to force the install of a .deb file.
instead of dpkg -i mypackage.deb, you write this:
dpkg -i –force-all mypackage.deb

This forces dpkg to install the deb file anyway.
