  Continue running under SSH?

  This session appears to be running under ssh. It is not recommended
  to perform a upgrade over ssh currently because in case of failure it
  is harder to recover.

  If you continue, an additional ssh daemon will be started at port
  '1022'.
  Do you want to continue?

  Continue [yN] y
