How do I get a version of this game running on Steam Deck without using the discover store?

[Jokerofspades]

so to keep a long story short, I play this game on a Steam Deck, me and my friends have a lot of fun playing together, recently they have started a modded server that doesn't work on 1.22, I need a way to get the 1.21 version of the game running and the discover store (which is normally how you run VS on Steam Deck) does not have the ability to downpatch apps, so is there a way for me to get a downloaded version of this game running on Steam Deck?

The discover store on steam deck is configured to only offer flatpak version of apps. While there is a way to downgrade flatpak apps, I get this error when I attempt to do so:

Error: While pulling app/at.vintagestory.VintageStory/x86_64/stable from remote flathub: Commit a1a19a47af15af5e8fb9985247c42d528e940b82d279c7e02ba0a12729c107df: GPG verification enabled, but no signatures found (use gpg-verify=false in remote config to disable)

So unfortunately, it looks like the maintainers of the flatpak version have disallowed pulling commits without a GPG keypair, meaning you'd have to be a maintainer yourself. It doesn't look like it's possible.

I don't think that's right... it's typically only pushing that's privileged. If nobody can pull, I don't think you'd be able to install the app at all. I found some hints on the internet that you just need to initialize Arch's keyring. This also doesn't entirely make sense to me, but there's multiple people saying it works so the incantation for it is:

sudo pacman-key --init && sudo pacman-key --populate

 

The other advice I see is removing and re-adding the remotes:

latpak remote-delete flathub
flatpak remote-delete flathub-beta
flatpak remote-add flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak remote-add flathub-beta https://flathub.org/beta-repo/flathub-beta.flatpakrepo

You can probably do it but it's likely to be more effort than it's worth. If it's a recent version, it's probably more reliable and easier to go the downgraded-flatpak route like hstone's thinking.
