Fedora Linux is another popular open-source Linux distribution targeted at desktop/laptop and server users who want cutting edge software in binary format. The latest version of Fedora is 32. Fedora version 32 released on April 28, 2020. This page shows you how to upgrade the existing version of Fedora Linux 31 to 32 using the dnf command.
Procedure to upgrade Fedora 31 to Fedora 32 Linux server
- Create a backup of your Fedora server or cloud box/VM.
- Upgrade all installed packages of Fedora version 31 by running sudo dnf upgrade --refresh command.
- Reboot the Fedora Linux system by tying the sudo reboot command if kernel update was installed.
- Install the Fedora update utility, run: sudo dnf install dnf-plugin-system-upgrade
- Start the upgrade procedure and download packages, run: sudo dnf system-upgrade download --releasever=32
- Reboot the box and complete upgrade, run: sudo dnf system-upgrade reboot
- Verify upgrades
Step 1 – Backup your Fedora server
You must keep backups of all critical data, files, and databases before you type any one of the following commands. In some cases, an upgrade may fail, and you can always go back to backups to restore your system or data. Next, I am going to log in to my Fedora server using the ssh command:
Step 2 – Update existing Fedora software and apps
It is time to apply and upgrade patches to already installed apps. Run the following dnf command:
sudo dnf update
## OR ##
dnf --refresh upgrade

Step 3 – Installing the DNF plugin on Fedora
We need to install a unique tool written in Python3 called python3-dnf-plugin-system-upgrade. It is nothing but a system upgrade plugin for the DNF command, which enables offline system upgrades using the “dnf system-upgrade” command. In other words, type the following command to install the same:
sudo dnf install dnf-plugin-system-upgrade
Step 4 – Upgrading Fedora 31 to Fedora 32 using the CLI
So far, we backed up and verified our Fedora box, applied all patches, upgraded apps, and installed the dnf plugin. It is time to download Fedora 32 packages and start the upgrade procedure by typing the following command:
sudo dnf system-upgrade download --releasever=32
You will be promoted as follows, and you need to type “Y” to continue with the upgrade procedure:
Before you continue ensure that your system is fully upgraded by running "dnf --refresh upgrade". Do you want to continue [y/N]: y
As soon as you confirmed upgrade, the dnf will begin downloading all of the upgrades for your server/desktop onto a local hard disk and prepare the update system:
Reboot to complete the upgrade procedure
Finally, you will get confirmation about downloads as follows:
Download complete! Use 'dnf system-upgrade reboot' to start the upgrade. To remove cached metadata and transaction use 'dnf system-upgrade clean' The downloaded packages were saved in cache until the next successful transaction. You can remove cached packages by executing 'dnf clean packages'.
In other words, we downloaded all updated packages for Fedora version 32. It is time to reboot the systems. Hence, type the following command:
sudo dnf system-upgrade reboot
Once the system restarted, the dnf will begin the upgrade process. It will take some time to install all those downloaded packages, so you have to wait. Here is a screenshot showing upgrade progress:
