It's easy to find out which version of Ubuntu you're running.

Just open up a command terminal and type:


lsb_release -a

You should see output similar to the following:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 10.10
Release:        10.10
Codename:       maverick

As you can see, the computer that I ran the lsb_release command on is running Ubuntu version 10.10.

There's also a command to find out which kernel you have.
