How to find out what version of Ubuntu you are running?

There are two ways of finding out what version of Ubuntu you are currently running on your system.

• Using the terminal:

        To use this method, open up a terminal and type the following command

        lsb_release -a

        

        It would give you the following output.

       

• Using the GUI

      Search for System Settings > Details. And, there you go! 

          

But I would recommend using the terminal, since it offers a much precise output.
