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.

Example output:

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:

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.
