Yup. There's two ways to do this:
If the updates set from GetUpdates can't be cherry-picked by the user,
we can emit a Message() with the type PARTIAL_UPDATES_NOT_ALLOWED or
something like that, which we can then catch in the GUI and hide the
An alternative, would be much simpler if it is always true for a
backend. Just don't implement UpdatePackages() -- just implement
I think that the moment, gpk-update-viewer might explode in a ball of
fire, but it would be really simple to just detect if UpdatePackages()
is implemented and if not, hide the checkboxes and use
pk_task_update_system() instead. I guess kpackagekit would need the
same fix if it doesn't do this already.
I guess it depends on whether we need to have all the updates done at
once every time, or just some times.
