Running an Ubuntu Server without a graphical interface is the best solution when you do not need any access to a desktop environment.
Ubuntu Server leaves away all the unwanted bells and whistles of a full desktop environment, all the security issues and the bloatware. So it is a good starting point that reduces the Ubuntu Operating System to what is basically needed.
All additions to that can be made later on the basis of how your requirements develop.
If at one time you need to add a desktop environment, it might be ideal not to fully add the complete Ubuntu Desktop Environment but a lightweight GUI like the GNOME minimal Desktop environment.
To install the GNOME Desktop on Ubuntu Server, simply add the following command:
sudo apt-get install xorg gnome-core gnome-system-tools gnome-app-install
Once the software has been transfered and is installed simply enter:
The system will reboot and start with the GNOME Desktop.
