What happens when when you run sudo apt-get update && sudo apt-get upgrade using a terminal? Can you edit your question with any errors or other issues that might come up? – Bruno Pereira Jan 10 '13 at 21:29

I would try to change the ubuntu mirror from where you're trying to download updates.

Open Software Sources and in the Ubuntu Software tab change the download from server to another one.

then try updating again.

Try this:

sudo apt-get clean
sudo apt-get update
sudo dpkg --configure -a
sudo apt-get clean
sudo apt-get autoclean
sudo apt-get update
sudo apt-get update -o Acquire::http::No-Cache=True
sudo apt-get clean
