LinuxQuestions.org - Problems/Errors with Sources.List

I'm trying to update my slightly outdated computer running a mix of debian stable/testing to completely testing. However, even though I only have one file open on sources.list I'm still getting errors.

aroot@raikunite:/home/knoppix# apt-get update

W: You may want to run apt-get update to correct these problems
E: Some index files failed to download, they have been ignored, or old ones used instead.

It's those to be precise. How can I get rid of those errors so I can finally run apt-get update and have it actually update! Thank you very much.
