Error after modifying sources.list

Question

I modified sources.list and now it wont load. I took everything out except for the first line and it still errors out. Any ideas based on it's output?

sources.list:

deb http://us.archive.ubuntu.com/ubuntu natty main

Output:

Ign http://us.archive.ubuntu.com natty InRelease

The sources.list generator at repogen looks to be a good way to get a customized sources file. Try using that to get a feel for the syntax and content of the file.

A proxy could be configured such that it wouldn't let you access the server. To fix this you must open /etc/apt/apt.conf and change or remove Acquire::http::Proxy
