What happens when you run the following?
sudo apt-get update

You may need to change which mirror you use. To change that, open up Synaptic Package Manager, hit Settings > Repositories. In the Ubuntu Software tab, change the Download From drop-down to Other, which will cause another window to pop up. In the new window, hit Select Best Server. This will select the one to which you have the fastest connection.
