I recently tried updating Easy Debian using Synaptic. It crashed, and I couldn't re-launch debian. I removed and re-installed it. It seemed fine, but when I tried installing Chromium, the install failed to download from the repositories. So, I had a look, and the active repositories were a mixture of Lenny, Lenny backports, and Squeeze. All US servers. Needless to say, attempting to update these failed.

So, here is the question:

Which repositories should be enabled in easy debian?
