Flathub is the central repo (more like app store for Linux) for Flatpak packages. It is a system for distributing desktop app that can run on almost any Linux distro. Here is the Flathub popularity by country. Image credit Reddit post https://www.reddit.com/r/linux/comments/1nle38v/flathub_popularity_by_country/#lightbox
@nixCraft It is worth noting that Flathub, like Snapcraft, AUR and PPAs, are _not_ actively vetted and that anything, including malware, can be published on them. In contrast, your old fashioned official deb repos have control over what is delivered.
Not saying these software sources are not useful, but be aware of the immense trust caveat.
@expiredtoken @nixCraft true, but on the other hand, Flatpak gives you quite good control over what an app can and cannot access. You can remove any permission at any time.
@piotrek @nixCraft That's true! I want both trust of source for the software, and easy to use constrain framework. With this respect, AppArmor is not easy, maybe Flatpak is more manageable.
