Fedora Linux 40 has arrived, and it comes packed with a host of new features and improvements. This release boasts GNOME 46 and KDE Plasma 6 for desktop systems and utilizes the Wayland graphics stack. Additionally, it includes integrated AI tools and updates to a wide range of open-source software packages.
Some of the standout enhancements include an updated Files app in GNOME 46, improved accessibility, a revamped Settings app, updates to key applications like Software, Maps, Calendar, and Extensions, and a general boost in system performance.
If you’re using Fedora 39, upgrading to Fedora 40 is a breeze. You can do it either through the command line or by using the GNOME Software graphical interface. Here’s how:
Upgrading via Command Line
1. Update Your System:
Before you start the upgrade, make sure your Fedora 39 system is completely up-to-date. Open your terminal and run:
sudo dnf upgrade --refresh
2. Install the Upgrade Plugin:
You'll need the `dnf-plugin-system-upgrade` to proceed. To install it, type:
sudo dnf install dnf-plugin-system-upgrade
3. Download Fedora 40 Packages:
Next, initiate the download of Fedora 40 packages with:
sudo dnf system-upgrade download --releasever=40
If you run into any software conflicts, adding the `--allowerasing` option can help resolve them:
sudo dnf system-upgrade download --releasever=40 --allowerasing
4. Reboot and Install:
After the download finishes, reboot your system to start the upgrade process:
sudo dnf system-upgrade reboot
Your system will begin the upgrade. Once it’s done, simply log in and check that everything is working correctly.
Upgrading via Graphical Interface
1. Notification and Preparation:
For those using Fedora Workstation, you should receive a notification about a new stable release. Click on the notification or open the GNOME Software app and head to the "Updates" tab.
2. Update Your System:
