Now that Fedora 34 is released with all of it's new goodies we will show you how to upgrade your system. This guide will show you how to upgrade your Fedora 33 (or earlier) system to the latest and greatest. We will be upgrading Fedora using the DNF package manager. Let's get started.

NOTE: Before doing any type of upgrade it is important to back up your data. Although this process is thoroughly tested, it is possible (albeit rare) that things can go wrong. BACK UP YOUR DATA!

Step 1: Elevate Your Privileges to Root

The first thing we want to do is become root. You can use su or sudo for this. 

su -

OR

sudo -s

Step 2: Upgrade All Current Fedora Packages

It is important to make sure you have the latest packages for all currently installed software. The DNF package manager provides a simple way to ensure this is done.

dnf --refresh upgrade

Step 3: Reboot Your System to Load Latest Kernel

Now we will reboot the system to ensure we have loaded the latest kernel. If you are sure you are already running the latest kernel, this step can be skipped. If you are unsure at all, it is advised to reboot.

Step 4: Install DNF System Upgrade Package

Now that your system is rebooted, switch back to root using just as we did in step 1. Your prompt should show a pound sign indicating you are root. Now we can using DNF to install the system upgrade plugin like so:

dnf install dnf-plugin-system-upgrade --best

Step 5: Download Fedora 34 Packages for Upgrade

Now we use the system upgrade plugin to download all the packages that are needed to upgrade to Fedora 34.

dnf system-upgrade download --refresh --releasever=34

Step 6: Start the Upgrade Process

Now we will use the DNF system upgrade plugin to start the upgrade. Be aware, the system will reboot during the upgrade process.

dnf system-upgrade reboot

Once the system reboots, it will automatically start the upgrade.
