app/com.jagex.launcher/x86_64/master not installed

[Manypopes]

I've tried to install the launcher as in the readme (and also tried the install script), but when I try to run the launcher with Flatpak I get the error "error: app/com.jagex.launcher/x86_64/master not installed". Any ideas what is causing this? Apologies if I'm doing something wrong here I'm not familiar with Flatpak.

Running Arch Linux on a Acer C720 Chromebook

Hello,

Sorry to hear about the issue you're facing. I think I see what's going on here. Flatpak can either install apps system-wide (the default if just running flatpak in a terminal) or user-wide (my installation instructions and script use the --user installation).

To my understanding, since you're used the install script, your flatpak run com.jagex.Launcher command is trying to find the default master branch from the system installation, which doesn't exist thus it errors out like we see above.

Does adding --user to your flatpak run command make it launch properly for you? Like:

flatpak run --user com.jagex.Launcher

Thank you, yes that was the issue, is launching properly now!

It ran properly once and tried to update, possibly having some more issues now but I'll mark this as closed :)
