I am planning to install Ubuntu on a Raspberry Pi substitute (Libre lePotato): https://hub.libre.computer/t/ubuntu-server-vs-desktop-vs-base/2218
The goal is to setup a portable MQTT server that stores data in a relational-database.
Mosquitto can be setup with the snap procedure.
mySQL can be setup with the snap procedure.
I would like to avoid reinventing the wheel: Is there an application that bundles MQTT and RDBMS?
