There are lots of software packages inside the Ubuntu repositories; they are divided into categories as follows:

  • Main: supported, free
  • Restricted: supported, non-free
  • Universe: unsupported, free
  • Multiverse: unsupported, non-free

You may also add 3rd-party repositories.

If you are using Ubuntu 11.04 or newer, your Ubuntu Software Centre is found in the applications directory.
