All I could find is how to make a list, and reinstall flatpaks from that list, as well as backup app data, however all of that assumes I want to do updates.

Meanwhile what I want is akin to extracting APK of a stable version of some app, backing it up and using it for years to come. For example that’s how I joined these 2 screenshots, using JointPics from 2014 which isn’t even on Play Store anymore, and targets API so low that it has to be installed via ADB. (Yeah, I am too dumb for GIMP)

As for the regression, you can see. On left is older Flatpak, on right is version from Arch repo. The Flatpak I originally installed as a hotfix for update that broke it completely at one point on Arch.
You can see the older version nicely fits the screen, splitting up text into columns.
Meanwhile the new version just does smaller page in middle of screen that doesn’t even work properly with Breeze Dark theme, causing different background for text sections.

The only improvement is ability to flip pages rather than use arrows, but that’s minimum.
Well, and maybe the progress keeping got fixed, but I didn’t test that much.

Don’t pay attention to the taskbar. I wish it could flip to vertical with different screen orientation. Yeah, the icons’ clickability is a dice roll of what you tap.

    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.
