How To Install Flatpak on CentOS Stream 10

CentOS Stream 10, the latest iteration of the popular Linux distribution, brings significant changes to how users manage desktop applications. One of the most notable shifts is the adoption of Flatpak as the recommended method for installing and managing software. This comprehensive guide will walk you through the process of installing Flatpak on CentOS Stream 10, configuring it for optimal use, and leveraging its capabilities to enhance your desktop experience.

Understanding Flatpak and CentOS Stream 10

Flatpak is a next-generation technology for packaging, distributing, and managing software on Linux systems. It offers several advantages over traditional package management systems:

• Sandboxed applications for improved security
• Consistent runtime environments across different distributions
• Easy updates and rollbacks
• Ability to run multiple versions of the same application

CentOS Stream 10 has embraced Flatpak as its primary method for desktop application deployment. This decision aligns with the distribution’s goal of providing a more modern and flexible desktop environment while maintaining stability and security.

Prerequisites for Installing Flatpak

Before diving into the installation process, ensure that your system meets the following requirements:

• A CentOS Stream 10 installation with internet connectivity
• Administrative (sudo) access to the system
• At least 500 MB of free disk space for Flatpak and its dependencies

It’s also a good idea to update your system before proceeding:

sudo dnf update -y

Installation Process

Step 1: Check for Existing Flatpak Installation

First, verify if Flatpak is already installed on your system:

flatpak --version

If you see a version number, Flatpak is already installed. If not, proceed to the next step.

Step 2: Install Flatpak Using DNF

To install Flatpak, use the DNF package manager:

sudo dnf install flatpak -y

This command will download and install Flatpak along with its dependencies.

Step 3: Add the Flathub Repository

Flathub is the primary repository for Flatpak applications. Add it to your system with the following command:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Step 4: System Reboot

While not always necessary, it’s recommended to reboot your system to ensure all changes take effect:

sudo reboot
