HI, I am going to use Ubuntu 20.04 but I do not know how to install Gnome 40. On the previous versions, I had no issue.
In the first step, update the system by running the following commands:
sudo apt update
sudo apt upgrade
sudo apt install tasksel
You can then run the following command to install the vanilla version of the GNOME desktop:
sudo apt install gnome-session gdm3
Also, you can use the following command to install GNOME desktop:
sudo tasksel install ubuntu-desktop
