A simple, lightweight distribution for 32-bit CPUs

You've reached the website for Arch Linux 32, the community maintained continuation of 32-bit support 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 pentium4 architectures. Also most(ly) non-graphical packages are available for i486, too. Have a look at the required cpu flags to decide which architecture is the right one for you. Most packages from Arch Linux's community-operated package repository are also compatible with Arch Linux 32.

Installation media which boot on i686 can be found here.

Join us on #archlinux32 IRC channel on Libera, check out our forums or subscribe to the mailing list to get your feet wet. Also glance through the Arch Wiki if you want to learn more about upstream Arch.

Changes to default password hashing algorithm and umask settings


With shadow >= 4.14.0, Arch Linux's default password hashing algorithm changed from SHA512 to yescrypt.

Furthermore, the umask settings are now configured in /etc/login.defs instead of /etc/profile.

This should not require any manual intervention.

Reasons for Yescrypt

The password-based key derivation function (KDF) and password hashing scheme yescrypt has been chosen due to its adoption (readily available in libxcrypt, which is used by pam) and its stronger resilience towards password cracking attempts over SHA512.

Although the winner of the Password Hashing Competition has been argon2, this algorithm is not yet available in libxcrypt (attempt one, attempt two).

Configuring yescrypt

The YESCRYPT_COST_FACTOR setting in /etc/login.defs is currently without effect, until pam implements reading its value. If a YESCRYPT_COST_FACTOR higher (or lower) than the default (5) is needed, it can be set using the rounds option of the pam_unix module (i.e. in /etc/pam.d/system-auth).

General list of changes

  • yescrypt is used as default password hashing algorithm, instead of SHA512
  • pam honors the chosen ENCRYPT_METHOD in /etc/login.defs and does not override the chosen method anymore
  • changes in the filesystem (>= 2023.09.18) and pambase (>= 20230918) packages ensure, that umask is set centrally in /etc/login.defs instead of /etc/profile

ansible-core >= 2.15.3-1 update may require manual intervention


As of ansible-core 2.15.3, upstream moved documentation and examples to a separate dedicated repository (see the related changelogs).
This means that, starting from version 2.15.3 the ansible-core package will stop shipping documentation and a default configuration example under /etc/ansible/ansible.cfg.

Regarding the documentation, it is available online: https://docs.ansible.com/
As for the configuration file, as explained in the wiki, a base config can be generated with the following command:

ansible-config init --disabled > ansible.cfg

After updating from ansible-core <= 2.15.2-1 to >= 2.15.3-1, everyone using a custom global Ansible configuration file stored under /etc/ansible/ansible.cfg will have their configuration saved as a pacsave file.
To restore it, run the following command:

mv /etc/ansible/ansible.cfg.pacsave /etc/ansible/ansible.cfg

budgie-desktop >= 10.7.2-6 update requires manual intervention


When upgrading from budgie-desktop 10.7.2-5 to 10.7.2-6, the package mutter43 must be replaced with magpie-wm, which currently depends on mutter. As mutter43 conflicts with mutter, manual intervention is required to complete the upgrade.

First remove mutter43, then immediately perform the upgrade. Do not relog or reboot between these steps.

pacman -Rdd mutter43

pacman -Syu

Shim packages required for 'icu'


If you see messages like:

:: installing icu (73.2-1.0) breaks dependency 'libicuuc.so=72-32' required by XXXX

you can work around this by forcefully uninstalling 'icu' (the 72 version) and installing 'icu'
(the 73 version) and 'icu72' (the 72 shared libraries) in parallel:

pacman -Rd --nodeps icu
pacman -Syy icu icu72
pacman -Syyu

Sadly we have big issues rebuilding packages at the moment, so this situation might persist for a while..
