Package Signing

Arch Linux ARM implements package signing following the model created by Arch Linux. All packages in all repositories for all architectures are signed by our build system; however, the repository database files are not signed in order to limit the exposure of private keys and because it is technically unnecessary.

Since all of the packages in our repositories originate from our build system — not from individual developers and maintainers — the packages are signed by the single build system key before leaving the secure build environment. Additionally, Arch Linux ARM mirrors are synchronized via rsync push from our master server, furthering the integrity of packages available for installation.

Enabling Signature Checking

  1. To help pacman-key work, ensure the haveged daemon is running. This daemon keeps the system's entropy pool full.
    systemctl status haveged
  2. If that command reports it active and running, go to the next step. Otherwise, install, start, and optionally enable haveged to run at boot:
    pacman -Syu haveged
    systemctl start haveged
    systemctl enable haveged
  3. Initialize the pacman keyring:
    pacman-key --init
  4. Install the Arch Linux ARM keyring:
    pacman -S archlinuxarm-keyring
    pacman-key --populate archlinuxarm
  5. Edit /etc/pacman.conf and uncomment or add the following lines:
    SigLevel = Required DatabaseOptional
    LocalFileSigLevel = Optional
