3. Article 12a: No posting your own photos or videos of sports matches. Only the "organisers" of sports matches will have the right to publicly post any kind of record of the match. No posting your selfies, or short videos of exciting plays. You are the audience, your job is to sit where you're told, passively watch the game and go home.

 Ubuntu is distributed on two types of images described below.

Desktop image
The desktop image allows you to try Ubuntu without changing your computer at all, and at your option to install it permanently later. This type of image is what most people will want to use. You will need at least 384MiB of RAM to install from this image.

Server install image
The server install image allows you to install Ubuntu permanently on a computer for use as a server. It will not install a graphical user interface.
