Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customize and alter their software in whatever way they see fit.
-
Ubuntu will always be free of charge, and there is no extra fee for the “enterprise edition”, we make our very best work available to everyone on the same Free terms.
-
Ubuntu includes the very best in translations and accessibility infrastructure that the Free Software community has to offer, to make Ubuntu usable by as many people as possible.
-
Ubuntu is shipped in stable and regular release cycles; a new release will be shipped every six months. You can use the current stable release or the current development release. A release will be supported for 18 months.
-
Ubuntu is entirely committed to the principles of open source software development; we encourage people to use open source software, improve it and pass it on.
Ubuntu is suitable for both desktop and server use. The current Ubuntu release supports Intel x86 (IBM-compatible PC), AMD64 (Hammer) and PowerPC (Apple iBook and Powerbook, G4 and G5) architectures.
Ubuntu includes more than 1000 pieces of software, starting with the Linux kernel version 2.6 and GNOME 2.24, and covering every standard desktop application from word processing and spreadsheet applications to internet access applications, web server software, email software, programming languages and tools and of course several games.
The Ubuntu Project is sponsored by Canonical Ltd. Canonical will not charge licence fees for Ubuntu, now or at any stage in the future. Canonical's business model is to provide technical support and professional services related to Ubuntu. We encourage more companies also to offer support for Ubuntu, and will list those that do on the Support pages of this web site.
