Arch Linux ARM relies on the package program Pacman, which was developed specially for the original distribution. Since Version 4 (2011), the software manager also supports inscribed packages so that the authenticity of downloaded packages can be checked. Official new packages from the Arch Linux team receive their digital signature during the creation process, before leaving the secure development environment, to prevent tampering and ensure maximum security. Using a single command “pacmand-Syu”, make sure that the Raspberry Pi operating system is on the must current update. The Arch Linux user community repository (AUR), which contains applications created by users, can be used to extend the package range.
To install Arch Linux ARM, simply download the corresponding tar.gz file for your Raspberry version and then extract it to a formatted SD card (minimum 2GB).
