Upgrading Gnome 40 on Debian 11

To install the latest version of Gnome on your Debian 11 operating system, you will need to enable experimental support. This is a straightforward process, and once done, you can install the latest version that Gnome has to offer.

Enable Experimental Repository

First, open up your terminal (CTRL+ALT+T), then you need to enable the experimental repository in sources.list as follows:

sudo nano /etc/apt/sources.list

You may need to use the su command to access root if you have not set up sudoers.

su

Now inside the sources.list file, add the following line:

deb http://deb.debian.org/debian experimental main

Now save the file (CTRL+O), then exit (CTRL+X).

Lastly, update your repository list:

sudo apt update

Now proceed to the installation part of the tutorial once complete.

Upgrade Gnome 40 & Dependencies

Now that you have the correct source to install the latest Gnome desktop, use the following command in your terminal to start the installation:

sudo apt -t experimental install gnome-session gnome-shell gnome-backgrounds gnome-applets gnome-control-center mutter gjs

As you can see, the command uses -t experimental to install the latest Gnome software from the experimental repository you added.

Once the Gnome Session manager has completed installing, reboot your Debian 11 operating system:

sudo reboot

Once you log back on, confirm the upgrade has been successful by typing the following command in your terminal:

gnome-shell --version

Example output:

GNOME Shell 40.2

Congratulations, you have upgraded to the latest Gnome 40 build.

How to Future Update Gnome 40

To update Gnome, all you need to do is run your normal apt update command as below:

sudo apt update

As you have installed Gnome from the experimental repository, any new updates to it will be picked up along with any other updates to your standard system packages. If updates are available, use the normal upgrade command:

sudo apt upgrade
