Step-by-step – Flatpak Installation in Linux Mint 20

GNU/Linux Mint 20 Installing Flatpak – QuickStart Guide

Hi! The Tutorial shows you Step-by-Step How to Install Flatpak in GNU/Linux Mint 20.x Ulyana/Ulyssa/Uma/Una LTS Desktop.

First, Flatpak for Linux Mint 20 is a technology for Building, Distributing, Installing and Running Linux Apps.

Moreover, Flatpak is primarily targeted at the Linux Desktop, although it can also be used as the basis for application distribution in other contexts, such as embedded systems.

Finally, Flatpak has been designed and implemented with a number of Goals:

• Allow applications to be installed on any Linux distribution.
• Provide consistent environments for applications, to facilitate testing and reduce bugs.
• Decouple applications from the operating system, so that applications don’t depend on specific versions of each distribution.
• Allow applications to bundle their own Dependencies, so that they can use libraries that aren’t provided by a Linux distribution, and so they can depend on specific versions or even patched versions of a library.
• Increase the security of Linux desktops, by isolating applications in sandboxes.
