This category contains articles about Arch Linux releases, and downloading and installing Arch Linux.

The installation media and their GnuPG signatures can be acquired from the Download page. The single ISO image supports both 32bit and 64bit systems.

Verify signature

It is recommended to verify the image signature before use, especially when downloading from an HTTP mirror, as these are run by volunteers who could serve malicious images.

On a system with GnuPG installed, do this by downloading the PGP signature (under Checksums) to the ISO directory, and verifying it with gpg --verify archlinux-<version>-dual.iso.sig. If the public key is not found, import it with gpg --recv-keys key-id.

Alternatively, run pacman-key -v archlinux-<version>-dual.iso.sig from an existing Arch Linux installation.

  • The signature itself could be manipulated if it is downloaded from a mirror site, instead of from as above. In this case, ensure that the public key, which is used to decode the signature, is signed by another, trustworthy key. The gpg command will output the fingerprint of the public key.
  • Another method to verify the authenticity of the signature is to ensure that the public key's fingerprint is identical to the key fingerprint of the Arch Linux developer who signed the ISO-file. See Wikipedia:Public-key_cryptography for more information on the public-key process to authenticate keys.

Installation methods

The table below offers an overview of the common ways to boot the installation media. As the installation process retrieves packages from a remote repository, these methods require an internet connection; see Offline installation of packages and Archiso#Installation without Internet access when none is available.

Method Articles Conditions
Write the image on flash media or optical disc, then boot from it.
  • Installation on one, or a few machines at most
  • Obtain a directly bootable system
Mount the image on a server machine and have clients boot it over the network.
  • Client-server model
  • Wired (1Gbit+) network connection
Mount the image in a running Linux system and install Arch from a chroot environment.
  • Replace an existing system with reduced downtime
  • Install on the local machine, or a remote one via VNC or SSH
Set up a virtual machine and install Arch as a guest system.
  • Operating system compatible with virtualization software
  • Obtain an isolated system for learning, testing or debugging
