How to reference flatpak apps?

Basic Help & Support Applications
1

I’d like to set a Flatpak app as the default web browser, but I don’t know how to reference it. The file is here:

/var/lib/flatpak/app

But when I try this:

net.waterfox.waterfox

I get an error:

[2] Sandbox: CanCreateUserNamespace() clone() failure: EPERM
Gtk-Message: 09:34:07.102: Failed to load module “canberra-gtk-module”

I’m assuming I’m referencing it incorrectly.

Thanks for your help.

Hi @begtognen ,

Welcome to the forum. :confetti_ball:

Install libcanberra and try again.

sudo pacman -S libcanberra

A clean way to run a flatpak.

flatpak run net.waterfox.waterfox

This gives you the list of installed flatpaks with names. Thats all you need to know realy. You dont need the path /var/lib/flatpak/app

flatpak list

Thanks so much, that worked perfectly.
