I have had problems updating NR on my machines before and so when I finally got a definitive command, I saved it and used it to update all machines.
bash <(curl -sL https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/update-nodejs-and-nodered)
Did that the other day on a RPI.
Still have 0.19.3
Can someone post what the definitive command is?
Slight hitch: Mostly for RPI, but also needs to accommodate NUC x86 machine running Ubuntu.
Ok, "definitive" may not be the exact word I want. But one which will update any/all of my machines.
If two commands are needed - one for RPI and one for NUC: fair enough.
