Flatpak is one of the most popular universal package formats on Linux. It allows you to install modern Linux apps without worrying about dependencies, distro versions, or broken packages. If you’re using a Chromebook with Linux enabled, installing Flatpak opens the door to hundreds of up-to-date apps from Flathub, including GIMP, OBS Studio, Spotify, Discord, and more.
ChromeOS does not support Flatpak out of the box, but thanks to the Linux Development Environment, setting it up is straightforward and completely safe.
Now, if you are here reading about how to install Flatpak on a Chromebook, we assume you want easier Linux app management and access to newer software versions. In this detailed guide, we’ll walk you through everything step by step.
What Is Flatpak and Why Use It on Chromebook?
Flatpak is a sandboxed app packaging system for Linux. Unlike traditional package managers, Flatpak apps run in isolated environments, which improves security and compatibility.
Using Flatpak on a Chromebook lets you:
- Install the latest versions of Linux apps
- Avoid dependency conflicts
- Use apps that aren’t available in default Linux repositories
- Easily manage and update apps from Flathub
For Chromebook users who rely on Linux apps, Flatpak is a big upgrade.
Things to Know Before Installing Flatpak
Before you start, make sure:
- Your Chromebook supports Linux Development Environment
- Linux is already enabled
- You have a stable internet connection
- You have at least 2–3 GB of free storage
If Linux is not enabled, Flatpak cannot be installed.
1. Enable Linux on Your Chromebook (If Not Enabled)
If Linux is already set up, you can skip this section.
- Open Settings on your Chromebook.

Flathub is where you’ll find most Flatpak apps, so this step is essential.
6. Restart Linux (Recommended)

Settings → Advanced → Developers → Linux development environment
