A simple, lightweight distribution

You've reached the website for Arch Linux, a lightweight and flexible Linux® distribution that tries to Keep It Simple.

Currently we have official packages optimized for the i686 and x86-64 architectures. We complement our official package sets with a community-operated package repository that grows in size and quality each and every day.

Our strong community is diverse and helpful, and we pride ourselves on the range of skillsets and uses for Arch that stem from it. Please check out our forums and mailing lists to get your feet wet. Also glance through our wiki if you want to learn more about Arch.

test-sec-flags: Call for Assistance


Inspired by discussions on the arch-general mailing list, test-sec-flags was created by pid1 (with help from anthraxx, strcat, sangy, and rgacogne) to test the performance impact of various security-oriented compilation and linking flags. The goal is to determine if these flags can be the new default for all Arch Linux packages. Preliminary results suggest that the performance impact is almost nonexistent compare to the compilation flags we already use, but we would like to collect and compare more results before moving forwards.

Download the source here and see the README for installation and usage instructions. The results subdirectory contains instructions on how to pull out the relevant statistics from the result files.

We are collecting results in the test-sec-flags wiki on Github. Please add your results there. In particular, we would very much like i686 results, as all of the previous contributors have been on x86_64 devices.

Patches welcome.

screen-4.4.0-1 unable to attach old sessions

Required update to pacman-5.0.1 before 2016-04-23


The release of pacman-5.0 brought support for transactional hooks. These will allow us to (e.g.) run font cache updates a single time during an update rather than after each font package installation. This will both speed up the update process, but also reduce packaging burden for the Developers and Trusted Users.

In order for the use of hooks to be started, we require all users to have updated to at least pacman-5.0.1 before 2016-04-23. Pacman-5.0.1 was released on 2016-02-23, so this will have given everyone two months to update their system.

PHP 7.0 packages released


Packages of the new major version of PHP have been released into the stable repositories. Besides the new PHP 7 features there are the following packaging changes. In general the package configuration is now closer to what was intended by the PHP project. Also refer to the PHP 7 migration guide for upstream improvements.

Dropping Plasma 4


Since the KDE 4 desktop has been unmaintained for several months and it's becoming increasingly difficult to support two versions of Plasma, we are removing it from our repositories. Plasma 5.5 has just been released and should be stable enough to replace it.

KDE 4 installations will not be automatically upgraded to Plasma 5. However, we recommend all users to upgrade or switch to a maintained alternative as soon as possible, since any future update may break the KDE 4 desktop without prior notice. See the wiki for instructions on how to upgrade to Plasma 5.
