Неспособный к init серверу: не Мог соединиться:В соединении отказано

Когда это выполняется,

#!/bin/bash 
#
# located in /lib/systemd/system-sleep/
# Created 4/2/19
exec 2> /tmp/systemd_suspend_test_err.txt
if [ "${1}" = "pre" ]; then
  # Do the thing you want before suspend here
  echo "we are suspending $(date)." > /home/andy/Downloads/message.txt
elif [ "${1}" = "post" ]; then
  # Do the thing you want after resume here
   echo "and we are back from being suspended $(date)" >> /home/andy/Downloads/message.txt
  #sleep 10
  #notify-send "Computer is returning from suspend." -t 2000
   gxmessage does NOT work and neither does inotify-send
  /usr/bin/gxmessage -fg red -font  'sans 30' -timeout 3  'Back from being suspended.'
fi

Я получаю это в /tmp/systemd_suspend_test_err.txt.
