Upgrade to GNOME 41 [duplicate]

Solution 1:

Gnome 40 is not officially supported in 21.04.

You can install it with a ppa, but it is not intended for productive use. Please carefully read the description of the PPA before proceeding.

WARNING: GNOME 40 is not yet officially supported in Hirsute Hippo. This PPA is just for testing. It breaks sometimes, especially when I'm upgrading the packages.

Also, you need to manually update mutter and install gnome-session, etc.
You should regard the additional Installation Instructions after adding the PPA.

sudo add-apt-repository ppa:shemgp/gnome-40
sudo apt-get update
