Installing via apt-get software causes issues.
I just installed debian stable and added repositories to install nvidia drivers and amarok. I have both the stable and testing repositories, with the stable commented out. Any time i try to install firefox, thunderbird, or pretty much anything else, it says that KDE, Gnome, the X Server, and about every installed program must be removed. I'd go through with the install, but this has happened before, and I don't know how to fix it. Any suggestions would be appreciated.
