Ubuntu is a collection of thousands of computer programs and documents by a broad spectrum of individuals, groups and businesses created.
Each of these programs may come under a different license. This policy describes the licensing that we follow in determining the software by default in Ubuntu operating system are included.Copyright licenses and brands are two different fields of law, and we consider them separately under Ubuntu. The following principles apply only to copyright licenses. We evaluate the brands in each case.
Categories of software in Ubuntu
Main, Restricted, Universe and Multiverse: thousands of software for Ubuntu are organized into four major groups or components.The software is in one of these components depending on the satisfaction of our philosophy of free software published, and the amount of support that can provide for them.This insurance covers only the software found in large and small, that contain software that is fully supported by the Ubuntu team and must comply with this policy.
Ubuntu component "main" of the licensing policyAll application software included in Ubuntu main component:Must include the source code. The most important component is the restriction that the non-negotiable and application software must be contained in it come with full source code.Must allow modification and distribution of modified copies under the same license. Only with the source code is not the same freedom, the right to change it. Without the ability to modify the software, the Ubuntu community can not support the software, fix bugs, translate or improve.
Ubuntu "main" and allow "limited" political componentAll software applications in large and small must meet the following requirements:Must allow redistribution. The right to sell or transfer the software alone or as part of an aggregate software distribution is important because:You, the user must be able to be a software that allows you to transfer or receive from the Ubuntu source code or compiled form.Although Ubuntu does not require licensing fees for distribution, you can download to print Ubuntu CD, or create your own versions of Ubuntu you are selling, and should be free to have to do so.If no fees or other charges for redistribution or modification.It is important that you exercise your rights to this software without paying for the privilege, and you can change to other uses on the same basis as this.Must ensure that these rights are provided with the software. You should be able to exactly the same rights to the software that we have to do.Must not discriminate against persons, groups or against fields of activity. The license of the software included in Ubuntu, can not be distinguished against a person or group of users and can not prevent users from using the software for a particular area of activity - for example a company. So you do not have to use the software, the license under the "free for non-commercial use."It should not be distributed under a license specifically for Ubuntu.The rights to the Software not depend on the program as an integral part of Ubuntu. So you do not use the software for which an exemption has Ubuntu is "special" or right to, and not put our own software in Ubuntu, and then denied the right to transfer.It must not contaminate other software license may licences.The no restrictions on other software distributed with her. For example, the license must not insist that all other programs on the same medium must be free software.May changes to the source, must be distributed as patches. In some cases, software authors happy for us to distribute their software and changes to their software as long as both are distributed separately, so that people always have a blank copy of their code. We are pleased that to make that adjustment.However, the license must explicitly permit distribution of software built from modified source code.
Documentation, firmware and drivers
Ubuntu contains licensed and copyrighted works, not the application software. For example, the default installation of Ubuntu documents, images, sounds, video clips and firmware.The Ubuntu community decides on the admission of this work on an individual basis to ensure that the work is not to limit our ability to Ubuntu for free, and you can continue to distribute Ubuntu.
The software that is installed by default
If you install Ubuntu, you normally need to install a desktop environment. It is also possible, a minimum of software (just enough to start the car) and then manually install the software to be installed with precision. The "Custom" to install, is usually due to server administrators, the only software you absolutely need to stay on the server rather preferred.All software applications installed by default is a free software.We have also install some hardware drivers that are available only in binary format, but these packages are clearly limited in the specified component.
