Well, it's almost 2 months ago when i installed knoppix onto my laptop, and when i make an apt-get update , it sees too many sources, and i don't know if i can eraise some of them, like the testing ones, nor the unstable...

A lot of Thanks To make That distro rules!

You need to put a # character in front of the lines which are causing the file not found errors in the sources.list then apt-get update again and they should go away. This is what I use for the sources.list and it gets me everything I want your needs may differ.
