GNOME 40 introduces many changes from visual changes, new apps, and overhaul back-end changes to improve performance. Overall, it is vastly different from what previous Gnome versions have looked before.
In the following tutorial, you will learn how to install the new GNOME 40 on your Ubuntu 21.04 operating system.
The tutorial is designed to upgrade your Ubuntu 21.04 operating system to the latest GNOME desktop offered by the creator of this Reddit post. GNOME 40 is not stable and is quite unstable given the frequent rebuilding that is done and can often break. To get a peak or use a system, you do not mind re-installing Ubuntu if things go pear shape. Be warned!

Install PPA for Gnome 40
The first step before installing Gnome on Ubuntu is to import the PPA ppa:shemgp/gnome-40. It must be noted this is not an official PPA and is maintained for upstream, which can break as described at the start of the tutorial.
To install the PPA, use the following command:
sudo add-apt-repository ppa:shemgp/gnome-40
Press the enter key to proceed.
Once imported, update your repository list to reflect the newly added PPA.
sudo apt update
Even on an up-to-date Ubuntu 21.04 operating system, you will find that after installing the PPA and using the apt update command, many packages will need to be updated.
126 packages can be upgraded. Run 'apt list --upgradable' to see them.
Before installing Gnome 40, you should upgrade these mostly dependency packages:
sudo apt upgrade -y
Next, remove and clean up unused dependencies that are leftover:
sudo apt autoremove -y
Installing Gnome 40
To install or upgrade Gnome is pretty straightforward. First, you must install the Gnome Window manager mutter using the following terminal command:
sudo apt install mutter
Next, install the gnome-shell and gnome-session packages:
sudo apt install gnome-shell gnome-session
Type Y, then press the enter key to proceed with the installation.
To verify the installation once complete, use the following:
GNOME Shell 40.3
Once everything is installed, you must restart your operating system for changes to take effect as follows:
sudo reboot now
Logging into Gnome 40
Once you are back in the login screen, which you will notice is quite different now, you will first need to click the little cog settings icon in the right-hand corner and select GNOME on Xorg. By default, it will have Ubuntu select, you must change this, or your desktop will not operate correctly.
Note, you can try GNOME, but it can still be unpredictable with Wayland. The worse case, go back to GNOME Xorg.
Once logging in, you will notice the Activities screen look has changed:
Now open the Applications Menu, you will notice even more improvements and changes. Doesn’t it look more pretty?
You can find more information about GNOME that was installed in the About Graphical UI on your Ubuntu 21.04 operating system:

sudo apt install screenfetch -y
