Look for the package update-notifier . Is it installed?

$ aptitude search update-notifier
i   update-notifier                 - Daemon which notifies about
i A update-notifier-common          - Files shared between

the 'i' means it's installed. If you have a 'p' it means it's not 
installed, but available.

install..

$ sudo aptitude install update-notifier

voilà
