I am a noob in Linux.
It would probably be better to start over than to try doing a massive un-install and re-install from another repository stream.
The Debian package management tools and control files do support such actions but you will see in their descriptions that Debian does not recommend trying it.
Next time, be a bit more careful of what repositories you specify.
