[SUCCESS] Installation Complete! so my process was

I reinstalled the Ubuntu 20.04 server on the VPS. I found the beta install.sh for Virtualmin 7 here

so to get this install.sh on the new server I entered the following

root@mail:~# wget -O virtualmin-install.sh https://raw.githubusercontent.com/virtualmin/virtualmin-install/d7fcb4ea35b5545417a38b7af4c4d97dbe45d591/virtualmin-install.sh

and to run the script

root@mail:~# /bin/sh virtualmin-install.sh

FYI - I found the instructions that ended with a failed install here

https://www.virtualmin.com/download/

I really appreciate all the effort that the teams put into making this software what it is.
Awesome! Thank you! David
