About Ubuntu

Ubuntu is a computer operating system based on the Debian GNU/Linux distribution. It is named after the Southern African ethical ideology Ubuntu ("humanity towards others") and is distributed as free and open source software. Ubuntu provides an up-to-date, stable operating system for the average user, with a strong focus on usability and ease of installation.

Ubuntu is composed of multiple software packages, of which the vast majority are distributed under a free software license (also known as open source). The main license used is the GNU General Public License (GNU GPL) which, along with the GNU Lesser General Public License (GNU LGPL), explicitly declare that users are free to run, copy, distribute, study, change, develop and improve the software. Ubuntu is sponsored by the UK-based company Canonical Ltd., owned by South African entrepreneur Mark Shuttleworth.
