MQTT broker on Ubuntu

[wpiman]

So I am not sure if anyone else ran into this: but I realized my MQTT devices stopped working about 2 weeks ago. I did some digging, and all my beacons stopped reporting around then. I thought maybe I got a new version of McsMQTT, then I thought it was maybe my RPIs died or needed rebooting. Finally, I couldn't connect from the local machine either. Ends up, I think I upgraded Ubuntu then and some of the default settings changed. I had to specify where the pid file went, make sure that directory was accessible and owned by moquitto. I also had to add a listener port to the conf file. Just a heads up if anyone else runs into this.

What version of Ubuntu are you running? Desktop or Server? I'd report this back to the package maintainers. It sounds like they may have clobbered your config. I've been running Mosquitto on Ubuntu 18.04.x (now at .6) without any issues.

22.04. Server I believe. I was at 20.04.4 before. The config file looked correct-- username and password were there. Just had to change the permissions and add a listener to the config file.

Ah Ok. I mis-understood. It wasn't like the upgrade package clobbered the config file. I suspect mosquitto got upgraded and while LISTENER used ti be optional, it is required with the latest version. I'll have to do a little digging into that since I'm getting ready to upgrade as well.
