Installing NaturalOne on Ubuntu - port in use

I am using Windows 10, Virtualbox 6.0.4, Ubuntu Desktop 18.10 64bit and Docker

I have successfully installed both Adabas and Natural, and have downloaded and unzipped the NaturalOne files.

I am trying to run the Setup.exe using Wine, but it defaults to C:/ as the installation drive (and doesn’t allow you to change it), after selecting the tick boxes and pressing enter I get the following message:
" The NaturalONE Community Edition can not be installed because at least on of the requested ports is already in use. First port in us: 10030"
This port doesn’t appear to be in use when I use netstat.

Any pointers would be appreciated
