You will need to pass I<--overwrite> if the previous upload was not
performed with dgit.
+If this is first ever dgit push of the package, consider passing
+I<--deliberately-not-fast-forward> instead of I<--overwrite>. This
+avoids introducing a new origin commit into the dgit view of your git
+history. (This origin commit would represent the most recent non-dgit
+upload of the package, but this should already be represented in your
+git history.)
