How to Install Arch Linux in Windows Subsystem for Linux

This updated guide explains how to install arch Linux in Windows subsystem for Linux with clear steps, practical tips, and useful context. While popular distributions like Ubuntu, Debian, and Fedora have been available on the Windows Subsystem for Linux (WSL) for a while, you can now officially install and use Arch Linux as well.

Setting Up Arch Linux on WSL2

Running Arch Linux on WSL 2 is now simple thanks to the official image. Still, ensure WSL is installed first. If you're not sure if WSL is installed, the easiest way to confirm and install it is via PowerShell.

Open PowerShell and run these command:

wsl --install --no-distribution

This command installs the WSL features and components required for GUI applications. Also, you may need to restart your system after the installation is complete.

After rebooting, open PowerShell again and install Arch Linux with these command:

wsl --install archlinux

This command downloads the official Arch Linux WSL image and sets it up as a new distribution in your WSL environment.

Once the installation is complete, you can launch Arch Linux with these command:

wsl -d archlinux

When you launch Arch Linux WSL for the first time, you need to update the package list and upgrade all installed packages to the latest version using these command:

sudo pacman -Syu

Confirm any prompts to continue syncing and upgrading. You can now proceed with installing additional software and customizing your environment using Pacman.

Limitations of Arch Linux WSL

While running Arch Linux on WSL 2 provides a powerful environment for many tasks, It is essential to note that this setup is not identical to a native Arch Linux installation. Many of the limitations arise because of the nature of running within the Windows ecosystem.

One notable limitation is support for Windows PCs running ARM. Currently, the official Arch Linux WSL images are primarily available for the amd64 architecture. That means users with Windows devices running ARM (such as some Surface Pro models or Dell XPSes with Snapdragon processors) may not be able to install and use the official Arch images. Still, other Linux distributions are available for ARM on WSL. The lack of an official ARM build reflects the focus of the standalone Arch Linux operating system on amd64.

Additional general limitations of WSL compared to native installations include lack of direct hardware access, limited kernel module support, nuances in systemd integration, and cross-filesystem performance issues. Still, for general development workflows, using command line utilities, and exploring Linux in general, Arch Linux on WSL 2 offers significant functionality.

The addition of an official Arch Linux image to the WSL lineup is a welcome development for any Linux user who appreciates Arch's philosophy and package management. Still, it is not a complete replacement for a native installation because of limited hardware access and lack of systemd support.

Still, if Arch Linux seems too advanced, you can consider trying Ubuntu or Debian on WSL as they are more beginner-friendly.
