Hi,
The instructions on this page for the installs are incorrect:

https://v2.openhab.org/download/

These 2 lines:

sudo apt-get update && sudo apt-get install openhab
sudo apt-get install openhab-addons

Should be changed to openhab2:

sudo apt-get update && sudo apt-get install openhab2
sudo apt-get install openhab2-addons

It will not work because you will be installing Zulu version 8 and then installing Openhab 3 instead of Openhab 2.

The pages for other operating systems are incorrect as well.

Thanks
