Flatpak is a package manager that is available for installation on CentOS Linux and all other major Linux distros. Flatpak offers CentOS users an alternative to the official repos and default dnf package manager as a source of software installation. Many applications available in Flatpak currently do not reside in official CentOS repos, making this a big benefit of installing Flatpak.
To use Flatpak on CentOS, we simply need to install the program, add the repos that contain the flatpak packages you wish to install, and then search for and install the packages. Flatpak will also let us manage and update the apps that we install. Flatpak works the same across all Linux distros, so you will only need to learn the command syntax once. The applications in Flatpak are also distribution independent.
In this tutorial, you will see how to install Flatpak package manager on CentOS Linux. Then, we will take you through some basic usage of Flatpak so you can get started with adding repositories and installing custom software of your choice.
Privileged access to your Linux system as root or via the sudo command.

Install Flatpak on CentOS step by step instructions
Follow the step by step instructions below to install Flatpak on CentOS, and get started with using the package manager to search for and install packages, or “flatpaks” on your system.
Installation of Flatpak on CentOS is very simple. Just open up a command line terminal and run the following command:
$ sudo dnf install flatpak
Next, you will need to enable one or more Flatpak repositories (referred to as “remotes” in Flatpak lingo). The biggest and best repository would be FlatHub. Enable it by executing the following command:
In order for the changes to take full effect, you will need to restart your system before using Flatpak:
$ reboot
Once your system boots back up, we are ready to install some applications. There are multiple ways to search for applications to install. One method is to pull up the FlatHub website in your web browser and find something you wish to install.

Once you identify the app you want to install, just click the ‘Install’ button in your browser.
Another way to search for an application would be to use the flatpak search command such as in the example below where we search for the ‘gimp’ application. This allows us to stay in our terminal instead of opening a web browser.
If you want to launch the installed application from terminal:
$ flatpak run org.gimp.GIMP
You can update all of your installed applications with:
$ sudo flatpak update
If, later on, you decide to remove an application, use the following command syntax. In this case, we will remove the GIMP program that we installed earlier.
$ sudo flatpak uninstall org.gimp.GIMP
To get a full list of all of your installed flatpaks, run:
In this tutorial, we saw how to install Flatpak on a CentOS Linux system. We also learned how to use Flatpak to add a software repository, install an application, update all installed apps, remove apps, and list the apps that are installed via Flatpak. Users love Flatpak because it is easy to install and run applications, and its built in sandboxing improves stability and security.
