Affects Version/s: None
Fix Version/s: None
error message can only be defined when transitioning from state AUTOMATIC_IN_PROGRESS to NONE in case of an error.
(corollaris: only when state is NONE can there be an error message)
error message can be cleared manually at any time.
error message is cleared automatically when:
- moving to AUTOMATIC_IN_PROGRESS
- moving to MANUAL_IN_PROGRESS
- changing edition without install
- restarting the server
