7 Welcome to UbuntuThis chapter provides an overview of the Ubuntu Project, andthe Debian Project upon which it isbased. If you already know about the Ubuntu Project s history and the Ubuntu distribution, feel freeto skip to the next What is Ubuntu ? Ubuntu is a complete Linux operating system, freely available with both community and professionalsupport. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that soft-ware should be available free of charge, that software toolsshould be usable by people in their locallanguage and despite any disabilities, and that people should have the freedom to customize and altertheir 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 makeour very best work available to everyone on the same Free terms. Ubuntu includes thevery best in translations and accessibility infrastructurethat the Free Softwarecommunity has to offer, to make Ubuntu usable by as many people as possible.

8 Ubuntu is shipped in stable and regular release cycles;a new release will be shipped every sixmonths. Every two even years an Ubuntu long term support (LTS) release will become available,that is supported for 5 years. The Ubuntu releases in between(known as development or non-LTSreleases) are supported for 9 month each. Ubuntu is entirely committed to the principles of open source software development; we encouragepeople to use open source software, improve it and pass it is suitable for both desktop and server use. The current Ubuntu release supports Intel x86(IBM-compatible PC), AMD64 (x86-64), ARMv7, ARMv8 (ARM64), IBM POWER8/POWER9(ppc64el), IBM Z zEC12/zEC13/z14 and IBM LinuxONE Rockhopper I+II/Emporer I+II (s390x). Ubuntu includes thousands of pieces of software, starting with the Linux kernel version andGNOME , and covering every standard desktop application from word processing and spread-sheet applications to internet access applications, web server software, email software, programminglanguages and tools and of course several Sponsorship by CanonicalThe Ubuntu Project is sponsored by Canonical Ltd ( ).

9 Canonical will notcharge licence fees for Ubuntu , now or at any stage in the future. Canonical s business model is toprovide technical support and professional services related to Ubuntu . We encourage more companiesalso to offer support for Ubuntu , and will list those that do on the Support pages of this web What is Debian?Debian is an all-volunteer organization dedicated to developing free software and promoting the ide-als of the Free Software community. The Debian Project beganin 1993, when Ian Murdock issued1 Chapter 1. Welcome to Ubuntuan open invitation to software developers to contribute to acomplete and coherent software distri-bution based on the relatively new Linux kernel. That relatively small band of dedicated enthusiasts,originally funded by the Free Software Foundation ( ) and influenced by the GNU( ) philosophy, has grown over the years into an organi-zation of around 1026 Debian Developers are involved in a variety of activities, including Web ( )and FTP ( ) site administration, graphic design, legal analysis of software licenses,writing documentation, and, of course, maintaining software the interest of communicating our philosophy and attracting developers who believe in the princi-ples that Debian stands for, the Debian Project has published a number of documents that outline ourvalues and serve as guides to what it means to be a Debian Developer: The Debian Social Contract ( ) is a statement of Debian scommitments to the Free Software Community.

10 Anyone who agrees to abide to the Social Contractmay become a maintainer ( ). Any maintainer can introducenew software into Debian provided that the software meets our criteria for being free, and thepackage follows our quality standards. The Debian Free Software Guidelines ( #guidelines) are aclear and concise statement of Debian s criteria for free software. The DFSG is a very influen-tial document in the Free Software Movement, and was the foundation of the The Open SourceDefinition ( ). The Debian Policy Manual ( ) is an extensive specifica-tion of the Debian Project s standards of developers are also involved in a number of other projects; some specific to Debian, othersinvolving some or all of the Linux community. Some examples include: The Linux Standard Base ( ) (LSB) is a project aimed at standardizing thebasic GNU/Linux system, which will enable third-party software and hardware developers to easilydesign programs and device drivers for Linux-in-general, rather than for a specific GNU/Linuxdistribution.
