Hallo,

vielleicht hilft dir ja das hier weiter, habs nur angelesen:

One of the great things about using open source software is the frequency with which bugs are fixed, security holes are patched, and new features are added. Ubuntu includes a very convenient update manager, which checks the software repositories for updates, and alerts you to install any new versions found. However, its default behavior of checking for updates every day annoys some people.
