The image will install openHAB 3 by default, to have it install openHAB 2 right from the beginning, set clonebranch=stable in nf before first boot. There's a high risk you mess up your system if you do. You can switch branches using menu option 01 in openhabian-config but ATTENTION you cannot up- or downgrade this way and you cannot arbitrarily change versions. If you need openHAB 2 support please use the stable branch of openHABian. OpenHAB 2 will continue to work on openHABian, but openHAB 2 support is no longer actively maintained and the software will only receive select patches deemed necessary by the maintainers of the project. When openHAB3 was released, there have been some big changes also to openHABian such as to install Java 11 and to use changed file and directory names so you cannot simple upgrade the packages without adapting the rest of your server system, the openHABian installation that is.
