Ryubing emulator was removed from flathub. Help me!

I was just casually installing updates through KDE Discover, then a message dialog appeared and said “Ryujinx (Ryubing) is no longer available due to a dmca takedown. Would you like to remove it?”.

First, I clicked “no” and clicked “refresh”, the “update” was still there. When I clicked “Update All”, it brought up that same dialog prompt.

So I clicked “yes” thinking it would only remove the update prompt, but nope it DELETED the ENTIRE application from my system.

Why? I don’t understand.

Isn’t there any way to just disable the update prompt?

And how do I get Ryubing emulator back?

If it was KDE Discover that was responsible for deleting it ENTIRELY from my system instead of just the reference, that’s so evil of them to do that.

I’m gonna ask about it on KDE discourse as well.

Please help me!!!

Well, as it was already mentioned, the application had to be removed due to a DMCA Takedown. So the application has been set to be EOL (end of life).

Now, Flatpak itself does not remove applications that are EOL. KDE Discover however does strongly encourage to remove unmaintained applications. That’s the prompt you have seen.

As for reinstalling it:
If it were a simple EOL, you could AFAIK still use the flatpak install command to install it, if you know the application id, as the application is only hidden.
That will probably not work though in this case, as when an application was removed due to an DMCA takedown, the application has to be removed from the servers.

The DMCA notice is about screenshots, but the app doesn’t build at the moment. It is still installable from the terminal.
