Only a very basic system is installed at this point. You will probably want to install all the modules. Alternatively, you can skip this and pick-and-choose the individual modules you want later.

Set up systemd (startup script)

If the Network/subnet is different then you need to run the below command to get the GUI access.

# ufw allow proto tcp from any to any port 80,443
