  This warning (not error) appears in journalctl log:

  smartmontools.service: Referenced but unset environment variable
  evaluates to an empty string: smartd_opts

  Fix:
  Add one line to /etc/default/smartmontools setting smartd_opts to an empty string

  Existing file /etc/default/smartmontools:

  # Defaults for smartmontools initscript (/etc/init.d/smartmontools)
  # This is a POSIX shell fragment

  # List of devices you want to explicitly enable S.M.A.R.T. for
  # Not needed (and not recommended) if the device is monitored by smartd
  #enable_smart="/dev/hda /dev/hdb"

  # uncomment to pass additional options to smartd on startup
  #smartd_opts="--interval=1800"


  File with fix (additional line) added:
  # Defaults for smartmontools initscript (/etc/init.d/smartmontools)
  # This is a POSIX shell fragment

  # List of devices you want to explicitly enable S.M.A.R.T. for
  # Not needed (and not recommended) if the device is monitored by smartd
  #enable_smart="/dev/hda /dev/hdb"

  # uncomment to pass additional options to smartd on startup
  #smartd_opts="--interval=1800"
  smartd_opts=""
