The issue here, and the cause of most of the annoyance when yet another of these problems turns up:I made some more changes to sources.list
Those two comments should be mutually exclusive, and seeing them in the same post makes me think: This is probably already beyond fixing.
If you don't know what you're doing, don't touch that file.
If you do know what you're doing, you probably won't want to in the first place.
Why? Because even if you put it back later, the damage is likely already done... and fixing a frankenDebian is a royal PITA.
Unfortunately, there is a lot of really bad advice floating about the 'net As soon as someone tells you to alter sources.list you should become extremely wary, particularly if it's to get a "newer version" of something.
