At least Fedora and Elementary have distro-made repos. They use them to package their apps for all distro versions without having to rely on Flathub infra and admins

It should. Install it to find out, you can keep both Bazaar and Discover while you make up your mind

I’ve never had an issue with the three banking apps I tried on LineageOS, and I didn’t even know there was a McDonald’s app or pokemon games.

If this list for /e/os roughly applies to LineageOS (with microG), I wouldn’t call it “only for secondary devices”, more “won’t work for some people”

Did I miss something? AFAIK google is requiring devs to ID, not to use SafetyNet or whatever the “only-runs-on-certified-phones” thing is called

If you already have the correct version of the flatpak installed, you can try flatpak build-bundle.

flatpak build-bundle LOCATION FILENAME NAME where

• LOCATION is the path of the repo on disk. Run flatpak info -l org.kde.arianna, and copy the part before /app
• FILENAME is the output file name, preferably .flatpak. Eg: arianna.flatpak
• NAME is the name of the app, here org.kde.arianna

The generated file can be installed with a double-click, or with flatpak install <file>

This is the equivalent of an Android .apk. It contains the app but depends on a runtime. If you want to install it in a few years, odds are the runtime will no longer be available. You can backup the runtime the same way with the --runtime option.

flatpak build-bundle --runtime LOCATION FILENAME NAME where

• LOCATION same as earlier
• FILENAME eg arianna-runtime.flatpak
• NAME is the name of the runtime, which you can get with flatpak info --show-runtime org.kde.arianna

This takes a while, for some reason. Maybe it’s compressing stuff?

The runtime is installed the same way as the app: double click or flatpak install.

Note: I only did this once, and not specifically on Arianna. Hope it works.
