Ahhhhhhhhhhhhh … no.

So. I put Ubuntu Core onto OPi Zero.

I snapped in Mosquitto and Node-Red.

Mosquitto is installed as a service, Node-Red is not.

I started Node-Red, set a graph up to send a timestamp every 5 minutes to debug via MQTT.

Left it all night.

In the morning the server was disconnected.  I did expect this if there was a snap update pushed through.

I did discover you cannot turn off updates … which many people are having concerns about.  Since the system could updated and reboot in the middle of something crucial.

The problem, I was expecting to log back in and simply restart Node-Red by TerraTerm console.

Not a sausage.

The serial port was still responding and putting out the IP address of the board.

I could ping the IP address but I could not log in.

I ended up having to pull the power to force a full reboot.

Not very useful.

Not even sure where to start.  Is this a problem with Ubuntu Core and Snap, a problem with the installed snaps, or are we back to the suspicions about the OPi Zero hardware?
