Hi Marci,

what I meant, is how did you update Node-RED on the Ubuntu environment?

remove the old-one first : **sudo apt-get remove nodejs**

and then install the new one : **sudo apt-get -y install nodejs**

that's it

nodejs != Node-RED.

Hopefully you can **sudo apt-get remove nodejs** and then run the Node-RED upgrade script  
[https://nodered.org/docs/getting-started/raspberrypi](https://nodered.org/docs/getting-started/raspberrypi) - which will install a LTS version of nodejs and then Node-RED.

All your work will be in your ~/.node-red directory - so back that up just to be sure -but the script doesn't touch it so it should come back ok.

Thanks marci and dceejay,

I am just VERY, VERY cautions as I can not be without the server.  
It controls too many Solar production, heaters and lights at the moment and I HAVE to upgrade to be able to use a subflow to restrict heater to only switch on during office hours.

I am considering to follow this cheat sheet
