Failed to fetch software updates.

I have Ubuntu 9.04 and when I try sudo apg-get update or if I try to use the update manager I get a problem.
I am running on a XPS M1530.

I usually get something along the lines of this:

Maybe the server you use is down or your internet connection fails to work.
Try another server instead or check if your connection is up.

i already tried switching servers and it still was failing to fetch updates.

For what it's worth,here some lines from my sources.list.

deb http://security.ubuntu.com/ubuntu jaunty-security main restricted
deb-src http://security.ubuntu.com/ubuntu jaunty-security main restricted
deb http://security.ubuntu.com/ubuntu jaunty-security universe
deb-src http://security.ubuntu.com/ubuntu jaunty-security universe
deb http://security.ubuntu.com/ubuntu jaunty-security multiverse
deb http://nl.archive.ubuntu.com/ubuntu/ jaunty-proposed restricted main multiverse universe
deb-src http://security.ubuntu.com/ubuntu jaunty-security multiverse

They seem a little different from yours.
