I tried to see if I could figure out a solution myself.
This first issue appeared to be:
E: Unable to locate package libmosquitto-dev
It appears that package isn’t available for the BeagleBone.
When I search, there are packages available with a slightly different name:
ubuntu@arm:~/OpenSprinkler-Firmware$ apt-cache search mosquitto
libmosquitto0 – MQTT version 3.1 client library
libmosquitto0-dev – MQTT version 3.1 client library, development files
libmosquittopp0 – MQTT version 3.1 client C++ library
libmosquittopp0-dev – MQTT version 3.1 client C++ library, development files
mosquitto – MQTT version 3.1 compatible message broker
mosquitto-clients – Mosquitto command line MQTT clients
python-mosquitto – MQTT version 3.1 client library, python bindings
So I tried installing libmosquitto0-dev:
sudo apt-get install libmosquitto0-dev
I thought I was on a winner, but unfortunately now I get a whole new set of errors:
ubuntu@arm:~/OpenSprinkler-Firmware$ sudo ./build.sh osbo

Done!
And so I am stuck again 🙁
