## Help Needed: Flatpak Error on Guix Running Hypixel HytaleLauncher

Hi everyone,

I’m having trouble running a Flatpak app on **Guix** and could use some help.

### What I did

I ran: flatpak run com.hypixel.HytaleLauncher

What happens

I get this output: (WebKitWebProcess:27): Gdk-WARNING \*\*: 00:38:36.188: Failed to read portal settings: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface “org.freedesktop.portal.Settings” on object at path /org/freedesktop/portal/desktop  
time=2026-01-20T00:38:37.161-03:00 level=INFO msg=“setting network mode” mode=online  
time=2026-01-20T00:38:37.161-03:00 level=INFO msg=“setting channel” channel=release current=  
Failed to call portal: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface ?org.freedesktop.portal.OpenURI? on object at path /org/freedesktop/portal/desktop  
ERR | Unable to open default system browser

What I think is happening

It looks like the Flatpak is trying to access **xdg-desktop-portal interfaces over DBus** , but the portal service isn’t exposing the interfaces it expects (Settings, OpenURI). Flatpak apps use these portals to open URLs, dialogs, and other desktop integration functions.

### My questions

1. What **portal packages** do I need installed on Guix to provide these interfaces?
2. Do I need to configure or start any **portal services** manually for Flatpaks to work properly?
3. Is there any **Guix-specific setup** required (for example in service definitions or session activation)?
4. How can I check that the portal is running and exposing the expected interfaces?

Thanks in advance!
