Can't open links from Flatpaks

[robschi]

Hello,

I am on Arch Linux with LXQt 1.2.0 and xdg-desktop-portal-lxqt 0.3.0-1 . When I click on a link in a Flatpak app I get the following error:

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

After installing "xdg-desktop-portal-kde" (with the additional dependencies "kactivities-5.103.0-1 kio-fuse-5.0.1-1 plasma-framework-5.103.0-1") and removing xdg-desktop-portal-lxqt, the error is gone and opening a link in an external application started to work.

Regards, Robert
