Have you tried apt-get update again at a later time?
I get this occasionally myself. I think this is server downtime or
maintenance. It never lasted longer than a few hours.

Your system isn't broken by the way. You can upgrade if you like, or
wait for a succesful update.

(of course there's always that little chance security.debian.org is
being compromised :-)
