This is a known transitional problem during the upgrade from GNOME
Shell and gnome-desktop3 3.34.x to 3.36.x. It will be resolved when the
transition finishes, but there is nothing that the maintainers of
individual packages can do about it right now.

Either hold/downgrade related packages to the versions that depend on
libgnome-desktop-3-18 for now, or upgrade selected packages to their
versions from unstable so that everything depends on libgnome-desktop-3-19.
