I think this should probably be fixed in SRUs together with bug 2006110 and verified together. See my comment 6 there for further comment.

See https://github.com/flatpak/flatpak/issues/5434 for reference. * This kind of issue may potentially affect more tools as well. [ Test Plan ] * Run "flatpak search firefox" - Observe the failure. * Update to the patched version * Run "flatpak search firefox" again, it should work now. [ Where problems could occur ] * The reverse-dependencies for appstream-glib in Ubuntu Jammy are: flatpak-tests unity libmalcontent-ui-0-0 libappstream-glib-dev gir1.2-appstreamglib-1.0 appstream-util flatpak * Flatpak should continue to work, and there should be no new errors in GNOME/Unity. [ Other Info ] * None. Updating this should mainly help Flatpak users and should have no ill effects on any other component of the OS.
