Step 2: Update Your Server

Before installing any package it is always recommended to run update once using apt update or apt-get update command. This will ensure the updation of all the packages with the latest version available on Ubuntu Repo.



Please note that here I am using root user to run all the below commands. You can use any user with sudo access to run all these commands. For more information Please check Step by Step: How to Add User to Sudoers to provide sudo access to the User.

You can also use an alternative method to install GNOME Desktop. If you have tasksel command available in your Server then you can simply run tasksel install ubuntu-desktop to install the full version of GNOME Desktop. If you don't have tasksel installed then you can install it by using apt install tasksel command.

root@localhost:~# tasksel install ubuntu-desktop
xserver-xorg install


Step 4: Login to GNOME Desktop

After successful installation you can login to GNOME Desktop using your GUI screen as shown below. If you don't see the GUI screen after GNOME installation then you can restart your Server once using reboot or init 6 command. In my case it came up immediately after installation so I don't have to restart. After login from the GUI, if you see any error then it means some of the packages did not installed correctly or may be partially installed. So in that case you need to check once.
