+Package is in NEW and has not been accepted or rejected yet.
+Unfortunately, we cannot determine automatically what should happen.
+You will have to pass either --deliberately-not-fast-forward or
+--deliberately-include-questionable-history to specify whether you are
+keeping or discarding the previously pushed history.
+
+The choice is important, to ensure that your git history is both
+suitable for public distribution and as useful as possible.  Please
