Menue "Add-on" : OWServer and 1wire Binding

Hello, I have installed and tested on a Rasberry Pi openhabian with the add-ons “OWserver Binding” and “1wire Binding”.

Now I have Ubuntu Server 17.10 with openHAB 2 installed on a virtual machine.

After installation, I see in the Addons menu entries “OWserver Binding” and “1 Wire Binding” not in the list. What can I do to select and install the entries?
Many Thanks! Matthias
