In this article, I will take you through 21 Popular flatpak command examples on Linux. If you are a Linux User/Professional then you might be aware of System Package Managers like dpkg, pacman, snappy, apk-tools etc. Flatpak is another very popular Package Manager which manages your application download, installation, running and removal on your Linux System.

You might be wondering why to use flatpak when you have other whole lot of Package Managers out there. Well, this is because flatpak comes with below added advantage over others.

  • Universality: Flatpak allows applications to be installed and run on virtually any Linux distribution. This includes non-GNU distributions, systemd-free distributions, distributions with a read-only operating system (OS), and various architectures without the developer needing the relevant hardware on hand.
  • Space for innovations: Flatpak facilitates distribution maintainers to focus on their goals to innovate their distribution.
  • Stability: breakage in a Flatpak application will not risk the system from breaking. This is because Flatpak applications and runtimes are contained to not interfere with the system altogether.
  • Rootless install: elevated privileges are not required when installing a Flatpak application or a runtime.
  • Sandboxed applications: one of Flatpak’s main goals is to increase the security of desktop systems by isolating applications from one another. This is achieved using sandboxing and means that, by default, applications that are run with Flatpak have limited access to the host environment. More on flatpak.

NAME
flatpak - Build, install and run applications and runtimes

SYNOPSIS
flatpak [OPTION...] {COMMAND}

DESCRIPTION
Flatpak is a tool for managing applications and the runtimes they use. In the Flatpak model, applications can be built and distributed
independently from the host system they are used on, and they are isolated from the host system ('sandboxed') to some degree, at runtime.

Flatpak can operate in system-wide or per-user mode. The system-wide data (runtimes, applications and configuration) is located in
$prefix/var/lib/flatpak/, and the per-user data is in $HOME/.local/share/flatpak/. Below these locations, there is a local repository in the repo/
subdirectory and installed runtimes and applications are in the corresponding runtime/ and app/ subdirectories
