Introduction
============
The Fedora Linux operating system is known for its frequent releases, bringing the latest features, improvements, and security updates to users. Upgrading your Fedora system is a crucial process to ensure you are benefiting from the latest advancements. In this guide, we'll explore the DNF system plugin, a powerful tool for upgrading your Fedora system seamlessly.
Understanding DNF System Plugin
-------------------------------
The dnf-plugin-system-upgrade is an essential component of the DNF package manager designed specifically for upgrading Fedora systems. It offers a reliable and efficient command-line method for transitioning your system to the most recent Fedora release. It's important to note that if you're using Fedora Silverblue or Fedora CoreOS, which utilize rpm-ostree, you should refer to the rpm-ostree documentation for upgrade instructions.
Preparing for the Upgrade
=========================
Before initiating the system-wide upgrade, it's crucial to back up your data. While the upgrade process is generally smooth, unexpected issues can arise, making data backup a necessary precaution. Downloading the Fedora Workstation Live image provides an additional safety net in case something goes wrong during the upgrade.
To ensure a successful upgrade, it's recommended to perform routine system updates using the following command:
``bash
$ sudo dnf upgrade --refresh
`
This step is essential for receiving signing keys of higher-versioned releases and addressing potential issues related to the upgrade process.
Installing the DNF System Upgrade Plugin
----------------------------------------
If you don't have the dnf-plugin-system-upgrade package installed, use the following command:
`bash
$ sudo dnf install dnf-plugin-system-upgrade
`
This plugin facilitates the download and installation of updated packages during the upgrade process.
Downloading Updated Packages
----------------------------
To download the updated packages for the desired release, execute the following command:
`bash
$ sudo dnf system-upgrade download --releasever=39
`
Adjust the release version as needed. Most users will upgrade to the latest stable release (e.g., 39). It's important to note that official support and testing cover upgrades across a maximum of two releases.
Managing Dependencies
---------------------
If any packages have unsatisfied dependencies, the upgrade process will prompt you to address this issue. Adding the --allowerasing option might be necessary in cases where packages from third-party repositories lack updated versions. Carefully review the output and consider using the --best and --setopt=keepcache=1 options for additional details and control.
Triggering the Upgrade
----------------------
Once the packages are downloaded, trigger the upgrade process with:
`bash
$ sudo dnf system-upgrade reboot
``
Be prepared for an immediate reboot into the upgrade process. Save your work and c
