Information about AvalancheOS, open-source software, third-party licenses, copyright, trademarks, and project materials.
AvalancheOS is an independent project focused on providing a portable, stateless Linux desktop environment. AvalancheOS Portable is distributed as a customized Linux operating system built from publicly available open-source software and other components that remain subject to their respective licenses.
AvalancheOS is not an official product of Canonical Ltd., Ubuntu, or any other third-party software project referenced on this website.
AvalancheOS is an aggregate distribution containing software developed by multiple independent projects. Individual applications, libraries, system components, drivers, fonts, and other included works may be distributed under different open-source or other licenses.
Nothing on this page is intended to replace, limit, or modify the license terms that apply to any individual component included with AvalancheOS. Where the license for a particular component grants rights that differ from the general statements on this page, the applicable component license controls.
Copyright and license information for installed software may be available in the AvalancheOS system, including within /usr/share/doc/ and the copyright or license files supplied by the respective software packages.
AvalancheOS includes software distributed under the GNU General Public License (GPL), including software originating from the Linux and GNU software communities. These components remain licensed under the terms of their respective GPL licenses.
The GPL grants users rights to use, study, modify, and redistribute covered software subject to the terms and conditions of the applicable GPL version. When GPL-covered software is redistributed, the applicable requirements concerning copyright notices, license terms, source code, and modifications must be respected.
AvalancheOS does not claim ownership of GPL-covered software or other third-party software included in the distribution. The copyright and licensing rights of the original authors and copyright holders remain in effect.
License and source-code information for installed GPL-covered packages may be available through the package repositories or the locations identified by the applicable software and package documentation. License information for installed packages may also be found within /usr/share/doc/ and the corresponding copyright or license files.
The GPL applies to the applicable software components; it does not automatically apply to AvalancheOS original branding, artwork, website content, or other independent project materials.
AvalancheOS contains software distributed under a variety of licenses, which may include the GNU GPL, GNU LGPL, BSD, MIT, Apache, and other open-source and free-software licenses.
Each component is governed by the license applicable to that component. Nothing in the AvalancheOS project is intended to remove or restrict rights granted by those licenses.
Users who redistribute AvalancheOS or create modified distributions are responsible for complying with the applicable licenses, copyright notices, attribution requirements, source-code requirements, and other conditions associated with the components they redistribute.
Where an applicable open-source license requires access to corresponding source code or preservation of license notices, AvalancheOS intends to provide or identify the appropriate source and licensing information in accordance with those requirements.
For installed packages, users should consult the package's documentation and copyright information, including the files provided under /usr/share/doc/, as well as the package repositories and upstream project documentation where applicable.
Because AvalancheOS is an aggregate distribution, the applicable license for an individual component controls that component's use, modification, and redistribution.
AvalancheOS Portable is based on Ubuntu Cinnamon. Ubuntu is an aggregate work containing software distributed under numerous individual licenses. Ubuntu's licensing and intellectual-property policies continue to apply to Canonical materials and trademarks, while the licenses of individual open-source components govern those components.
