wget http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key
sudo apt-key add mosquitto-repo.gpg.key
cd /etc/apt/sources.list.d/
sudo wget http://repo.mosquitto.org/debian/mosquitto-jessie.list

I note this is still picking up the Jessie repo. Is this because this instruction has not been updated or is it deliberate? As mentioned elsewhere, the Stretch version from the mosquitto.org repo does not work out of the box as it has some bad dependencies. I used the package direct from the Debian/Raspbian repo.
