How do I upgrade to Ubuntu 10.04.1 LTS [duplicate]

I want upgrade from Ubuntu 10.04 LTS to Ubuntu 10.04.1 LTS. Is there a basic update? How do I do it?

If you've been installing updates via the Update Manager or apt then you're probably already running 10.04.1. You can confirm your version by executing lsb_release -a on the command line.

The official documentation for upgrading can be found here.

The release of Ubuntu 10.04.1 LTS is basically only an updated installation CD. If you have a completely updated installation of Ubuntu 10.4 LTS, you are effectively running Ubuntu 10.04.1 LTS.

Unlike other release updates, maintenance updates don't display a special prompt in the Update Manager so it's easy to not even notice when they're installed.
