Upgrading GNOME on Debian

The stable version of Debian often comes with an old GNOME version due to its focus on stability. For example, GNOME Debian 12 latest update comes with GNOME 43. The newest version of GNOME, as of writing this post, is 46. The latest versions of GNOME loaded so many innovative features. Debian 12 users can't simply update to GNOME 46. Here are the steps to update to GNOME's latest version. Debian 12 is used to demonstrate the update process. I request that the process be tried in a Debian 12 installed in Virtualbox for learning purposes and later tried on the production computer. Take the data backup before the update attempt.

Two ways we can do the GNOME update. Install the Debian 12 without any desktop. While software selection, uncheck the Debian Desktop environment and GNOME to get desktopless Debian.

Start the installation directly if you are using the Debian stable version with a desktop. Anyway, start the update process from here.

Speed up updates in Linux Mint

Software repositories are computers located in various places. Indian Linux users can select servers located in India to download and install packages to keep the system new. Linux Mint allow the users to select fastest software repository and speed up the update process. This feature facilitates the packages download speedy manner. Otherwise, need to stick on with slow software repository and wait more for downloading the package updates.

Open Application Launcher > Administration > Software Sources.

The Software Sources will open up. Two sources available, one for Linux Mint and another for Ubuntu. We need to select fast sources for our computer.

 Click on Mirrors and find the fastest mirror accessible from your place.

Select the software repositories for both Linux Mint and Ubuntu. Open Terminal and apply following commands to update the system.

sudo apt update
sudo apt upgrade
