# Supported images
You can download (opens new window) and use server, desktop or minimal. If you choose a minimal image, you need to install armbian-config first.
sudo apt-get update
sudo apt-get upgrade
- Run armbian-config
Select OpenHAB2 (old version) or OpenHAB3 with SPACE and press ENTER
Wait 5 to 10 minutes depending on your hardware. During this time you can leave armbian-config and check if installation was successful by checking what openhab is doing on the system:
sudo htop -u openhab
If you don't see any openhab activities, something went wrong.
