On Ubuntu 18.04 daily with flatpak 0.11.3, gnome-software-plugin-flatpak 3.28.0 I have not been able to reproduce this issue. I did have a separate issue, which looks like a bug in cleanups between versions of gnome-software as removing all apps, remotes and caches resolved the issue - I have reported this upstream https://gitlab.gnome.org/GNOME/gnome-software/issues/328.
On Ubuntu 17.10, with flatpak 0.8.9 (which I am in the process of SRU'ing - bug 1752381) and gnome-software-plugin-flatpak 3.26.1 I am able to reproduce the issue - "failed to get related refs: using origin io.github.GnomeMpv-origin: Remote "io.github.GnomeMpv-origin" not found".
This appears to be an issue with gnome-software-plugin-flatpak, not flatpak itself - I have spoken to hugsie and kalev upstream and they confirmed this. It was also stated that "flatpakrefs in 3.26.1 are known buggy." and "I'd suggest retesting with 3.28.0 or 3.26.7" - 3.28.0 appears to have resolved the issue, 3.26.7 probably needs a SRU? Therefore I am marking this bug as invalid for flatpak.

Furthermore I have added a test for installing flatpakref's with gnome-software to the test plan for future flatpak releases https:/ /wiki.ubuntu. com/Process/ Merges/ TestPlan/ flatpak once this bug has been resolved.
