Does sources list mess require fresh install

[LL Phillips]

Thanks for your reply.  Below is my sources list now but I think I'm in 
more trouble than I know and will have to learn how to reformat and 
reinstall because showing in my top right hand corner is a red & white 
one-way sign , meanwhile the video is complaining about low-resolution 
so I need to use the console startx login.  There is a new release of 
CANTA anyway so maybe I'll be better off.

OK, firstly, what lines were changed?

Secondly, did the canta repository add files that were in other
repositories that make it difficult to back out the changes? This is
assuming you actually installed from that repository.

Deleting the repository is simple - just edit the file as root, place
a # (comment) in front of the deb and deb-src lines for that
repository, and then save & quit, then do "aptitude update" as root.
