As part of different tests on real devices (I tested this in krillin), sporadically we face the following exception trying to reset the ubuntu keyboars.
input.Keyboard.create('OSK')._keyboard.reset()
Traceback (most recent call last):

Original exception was: ("Search criteria (connection name = 'org.maliit.server', object path = '/com/canonical/Autopilot/Introspection') returned no results", 'Unable to find maliit-server dbus object.

In other similar situations we also got ProcessSearchError
