systemctl / mosquitto service is not a native service / RPI debian stretch

[Alex-Lewa-95-RPI-Noob]

How to solve following problem:

(Screenshot from the android app Admin Hands.)

After you type sudo systemctl enable mosquitto.service the console shows mosquitto.service is not a native service, redirecting to sytemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install enable mosquitto.

1. Type wget http:https://repo.mosquitto.org/debian/mosquitto-repo.gpg.key sudo apt-key add mosquitto-repo.gpg.key.
2. Make the repository available to apt so type cd /etc/apt/sources.list.d/.
3. Type sudo wget http:https://repo.mosquitto.org/debian/mosquitto-stretch.list.
4. Type cd.
5. Type sudo apt-get update
6. Type sudo apt-get install mosquitto
7. Perhaps type sudo reboot and restart your ssh if you should use it.
8. Type sudo systemctl enable mosquitto.
   Sorry, I forget something with dpkg.

you don't need to do anything. it's a notice about infrastructure.
