If you did not add any external package sources, this may be a temporary problem.
Wait some time, run "sudo apt-get update" in the Terminal and try to update again.
If it persists by tomorrow, there is something else wrong.

If you have added external package sources, please provide the full output of these three commands:
egrep -r '^deb' /etc/apt/
apt-key list
sudo apt-get upgrade

Thanks!
