I managed to walk through the update script "update-nodejs-and-nodered.sh" and get back up and running, with everything up to date.

May 28 13:53:04 myPi512 Node-RED[606]: 28 May 13:53:04 - [info] Node-RED version: v1.3.5

May 28 13:53:33 myPi512 Node-RED[606]: 28 May 13:53:33 - [info] Dashboard version 2.29.1 started at /ui
I downloaded: node-v10.24.1-linux-armv6l.tar.xz
~ /home/pi/ I did: sudo tar -xf node-v10.24.1-linux-armv6l.tar.xz --strip-components=1 -C /usr 2>&1 | sudo tee -a /var/log/nodered-install.log >>/dev/null
There must be an issue into looking at "latest". 6l isn't there.
There's a more recent version for 6l. https://nodejs.org/dist/latest-v11.x/node-v11.15.0-linux-armv6l.tar.xz I haven't tried that one.
The update script removed node.js and wasn't able to install it or continue with an update. "install node.js failed X"
Thanks.
Please advise.
