Ubuntu Server is a variant of the Ubuntu OS that does not include a graphical user interface (GUI) by default. GUI applications use system resources required for server-oriented tasks, so Linux server distributions are usually installed with minimal setup or no GUI installed.
However, some tools perform better and are easier to manage with a GUI. If you use a tool with a GUI, installing a desktop environment can improve the experience of working with the server.
This guide will show you how to install a desktop graphical interface (GUI) on your Ubuntu server.
1. Update the Ubuntu OS and package with the following :
# sudo apt update && sudo apt upgrade
2. Install Ubuntu Desktop by running the following command:
# sudo apt install ubuntu-desktop
3. Reboot the system when the installation finishes by typing:
# sudo reboot
