[vpsdeploy]

Not with NX...

1- Create this file and run it
2- Reboot the server
3- Connect via VNC -> IP.of.the.server:1

The graphical install is waiting your VNC connection.

Hi,

create a new file:

setup.sh with the content of the script
Do a chmod 777 setup.sh
Run "sh setup.sh"
And reboot
Wait for server reboot
Connect via VNC -> IP.of.the.server:1

Regards
