Title:
  apt-key does not output to non-terminals

Status in apt package in Ubuntu:
  Confirmed

Bug description:
  A common idiom for checking fingerprints for keys begins with:
  ' apt-key fingerprint $key|grep fingerprint|...'
  ... this works up to thru jessie at least.. in zesty apt-key gives a 'warning' but produces no output.

  "Warning: apt-key output should not be parsed (stdout is not a terminal)"
  If the lack of output is intended and is meant to be a proscription, it is overreaching at best. A warning makes perfect sense.
