Hi,  
Just curios to know why node-red won't start when installing versions newer than 2.9.5 of the node-red-dashboard, 2.9.5 works fine.  
I guess either node-red or node.js or both have to be updated or?  
The error turns out that the dashboard folder is removed and the nodes cannot be found. This is what the syslog says

The version of nodejs you have is well beyond end of life and is no longer supported. Newer versions of dashboard require a more recent nodejs.

You are also using a very old version of Node-RED when you upgrade nodejs also spend the time to upgrade Node-RED
