You can check it via command line.

  1. Open a Terminal by pressing CTRL+ALT+T.

  2. Type: 

    lsb_release -a

    and press Enter.

  3. The Ubuntu version is displayed on the 'Description:' line.

Will this command differentiate the alpha/beta/prod release? – devav2 Oct 22 '12 at 8:24

This works for most of the linux distros.

cat /etc/issue

Run this in a shell.

There are GUI ways of checking but I prefer the Terminal.

To check your Ubuntu version using the command line:

  1. Open a Terminal by pressing Ctrl+Alt+T.
  2. Type: lsb_release -a and press Enter.

The Ubuntu version is displayed on the 'Description:' line.
