How To Find Flatpak Applications Using A Specific Runtime In Linux

This guide explains how to find Flatpak applications using a specific runtime. Let's streamline the text and improve clarity.

Finding Flatpak Applications Using a Specific Runtime

Flatpak, a popular Linux application packaging system, uses runtimes to provide applications with necessary libraries and environments. This guide shows you how to identify which Flatpak applications utilize a particular runtime.

1. Listing All Installed Applications

To view all installed Flatpak applications, use this terminal command:

flatpak list --app

This displays a list including runtime and SDK information for each application.

2. Finding Applications Using a Specific Runtime

To pinpoint applications using a specific runtime (e.g., org.freedesktop.Platform), filter the output:

flatpak list --app --columns=application,runtime | grep "org.freedesktop.Platform"

This command shows only applications utilizing the specified runtime.

Example Output:

<code>com.anydesk.Anydesk    org.freedesktop.Platform/x86_64/24.08
com.github.marktext.marktext    org.freedesktop.Platform/x86_64/23.08
...</code>

3. Searching Remote Repositories (e.g., Flathub)

To search for applications in a remote repository (like Flathub) that use a specific runtime:

flatpak remote-ls flathub --app --columns=application,runtime | grep "org.freedesktop.Platform"

This lists applications from Flathub using the specified runtime. To list all applications from Flathub:

flatpak remote-ls flathub --app

4. Checking a Specific Application's Runtime

To check the runtime of a single application (e.g., org.mozilla.firefox):

flatpak info org.mozilla.firefox

This provides detailed application information, including the runtime used.

Example Output (Partial):

<code>...
Runtime: org.freedesktop.Platform/x86_64/23.08
...</code>

Summary

These flatpak commands efficiently identify Flatpak applications using a specific runtime:

• List all installed: flatpak list --app
• Filter by runtime: flatpak list --app --columns=application,runtime | grep "runtime-name"
• Search remote repositories: flatpak remote-ls repository-name --app --columns=application,runtime | grep "runtime-name"
• Check specific app: flatpak info application-id

Use these commands to easily manage and troubleshoot your Flatpak applications.
