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 x86-64 architecture. 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.

Increasing the default vm.max_map_count value


The vm.max_map_count paramater will be increased from the default 65530 value to 1048576.

This change should help address performance, crash or start-up issues for a number of memory intensive applications, particularly for (but not limited to) some Windows games played through Wine/Steam Proton. Overall, end users should have a smoother experience out of the box with no expressed concerns about potential downsides in the related proposal on arch-dev-public mailing list.

This vm.max_map_count increase is introduced in the 2024.04.07-1 release of the filesystem package and will be effective right after the upgrade.

Before upgrading, in case you are already setting your own value for that parameter in a sysctl.d configuration file, either remove it (to switch to the new default value) or make sure your configuration file will be read with a higher priority than the /usr/lib/sysctl.d/10-arch.conf file (to supersede the new default value).

The xz package has been backdoored


TL;DR: Upgrade your systems and container images now!

As many of you may have already read (one), the upstream release tarballs for xz in version 5.6.0 and 5.6.1 contain malicious code which adds a backdoor.

This vulnerability is tracked in the Arch Linux security tracker (two).

The xz packages prior to version 5.6.1-2 (specifically 5.6.0-1 and 5.6.1-1) contain this backdoor.

The following release artifacts contain the compromised xz:

  • installation medium 2024.03.01
  • virtual machine images 20240301.218094 and 20240315.221711
  • container images created between and including 2024-02-24 and 2024-03-28

The affected release artifacts have been removed …

mkinitcpio hook migration and early microcode


With the release of mkinitcpio v38, several hooks previously provided by Arch packages have been moved to the mkinitcpio upstream project. The hooks are: systemd, udev, encrypt, sd-encrypt, lvm2 and mdadm_udev.

To ensure no breakage of users' setup occurs, temporary conflicts have been introduced into the respective packages to prevent installing packages that are no longer compatible.

The following packages needs to be upgraded together:

  • mkinitcpio 38-3
  • systemd 255.4-2
  • lvm2 2.03.23-3
  • mdadm 4.3-2
  • cryptsetup 2.7.0-3

Please note that the mkinitcpio flag --microcode, and the microcode option in the preset files, has been deprecated in favour of a new …

Making dbus-broker our default D-Bus daemon


We are making dbus-broker our default implementation of D-Bus, for improved performance, reliability and integration with systemd.

For the foreseeable future we will still support the use of dbus-daemon, the previous implementation. Pacman will ask you whether to install dbus-broker-units or dbus-daemon-units. We recommend picking the default.

For a more detailed rationale, please see our RFC 25.

Bugtracker migration to GitLab completed


We are happy to announce that the migration of the bugtracker to GitLab is done! 🥳

Thanks to everyone who has helped during the migration!

This means the issue tracker and merge requests on the GitLab package repos are now enabled.

The old bugtracker will subsequently be closed down. For archiving reasons there will be a static copy so that links (for example the randomly picked Task #56716) are still stable, migrated bugs have a closing comment pointing to the new URL on GitLab.

Packaging bugs are now opened on the repo hosting the corresponding packaging sources, the "Add …
