How to Update Arch Linux

  1. Research the upgrade. Visit the Arch Linux homepage, to see if there have been any breaking changes to packages that you have installed recently. If there are, there may be manual intervention required after the upgrade.

  2. Update the package databases for each of the repositories on your system.

    $ sudo pacman --sync --refresh
    
  3. Update the local database of PGP keys used by the package maintainers. This step is optional, but may prevent problems later on with the upgrade if the database has not been updated for some time.

    $ sudo pacman --sync --needed archlinux-keyring
    
  4. Upgrade all system packages. Be sure to note the upgraded packages and any output that requires your attention during the upgrade process.

    $ sudo pacman --sync --sysupgrade
    
  5. Reboot the system.

    $ sudo reboot
