Installation via images
Prepare the image
Etcher can also be used to transfer ARM images into SD cards.
Boot the installer
ARM images are ready to go, so boot from SD card and wait for the initial setup to complete. This takes around 30 minutes on slow devices like Raspberry PI.
Warning
Do not shut down the system during the initial setup. Give the system enough time to finish the setup stage, otherwise the system will be in a broken state.
