About Ubuntu

Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things

Why its hard to update

Upgrading Breezy to Dapper via apt-get can be problematic. If you just installed Breezy then why not just burn a Dapper CD and install it. I had all sorts of problems considering the upgrade from Breezy to Dapper. There were issues with the X server that had to be configured, applications launched slower, and many other problems. Upgrading can also place holes in your OS so the best option is probably to just install Dapper fresh.
