Update Fedora 39 over command line

 Fedora 39 includes several new features and improvements, including:

• The latest GNOME 45 desktop environment, with stylish new widgets, a brand new Image Viewer app, and many other refinements.
• The Linux kernel 6.5, with support for the latest hardware and security features.
• The Firefox 110 web browser, with improved performance and security.
• The LibreOffice 7.5 office suite, with new features and bug fixes.

Step 1: Update Fedora 38 (Required)

Before moving to the new version, it’s important to update your Fedora 38 system packages to most latest and most compatible versions.

sudo dnf upgrade --refresh

Step 2: Install the DNF-plugin-system-upgrade Package on Fedora

Once the system upgrade is completed, you can install the dnf-plugin-system-upgrade plugin, which is a command-line tool for upgrading Fedora systems to a new major release.

sudo dnf install dnf-plugin-system-upgrade

Step 3: Download Fedora 39 Release

Now it’s time to use the system-upgrade command to download the Fedora 39 release.

sudo dnf system-upgrade download --releasever=39

If you encounter conflicts during the upgrade, consider adding the --allowerasing option to your upgrade command, which will enable DNF to remove packages that could be causing conflicts during the upgrade.

sudo dnf system-upgrade download --releasever=39 --allowerasing

After the package download is complete, restart your system to begin the final installation process.

sudo dnf system-upgrade reboot

Step 4: Verify Fedora 39 Release

Once the upgrade to Fedora 39 is done, and you log in, you’ll see some changes in the user interface.
