I'm running Ubuntu 10.10 Netbook on my Toshiba NB305. For the most part it's a great system and I hope to never again have to use the OS that came pre-installed (which wasn't Ubuntu).

Little problem with Update Manager though. When I hit the Authenticate button the system seems to just hang there. No progress bar, nothing -- just the spinning cursor indicating that the system is doing something.

On my other machine, Update Manager will tell me that the updates have been successfully downloaded, and there's a Done button. But not on the netbook version.

Has anyone else encountered this?
