Double checking how to update 2 machines

General
1

I know I should know as I just did it to one of my RasPis the other day.

But my memory is not that good just now, so want to check again.

Machine specs:
RasPi3 B + Buster
NodeJS V16
NR 3.0.x

I want to update and get NR V4.x installed.

So the command I need is:
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered) --node18

I'm also wanting to migrate to Dashboard-2 from the older one.

As that is a different name, I guess they can co-exist and as I get rid of all the older Dashboard nodes, when complete I can delete it altogether - yes?

Yes, they are independant meaning you can migrate at your own pace.

Why node 18? It is EOL next month!

Buster doesn't support V20. So unless I update the O/S......

:frowning:

Debian 10 based "Buster" reached its Long Term Support (LTS) end-of-life on June 30, 2024

You are playing with fire!

Well, the other day one of my machines (of the 3 Raspis) kinda fell over at the NR level.

So I rebuilt it with the newer version of NR. But the existing Node.js is 16.x.

I tried with the --20 option but it failed.

It was mentioned that version 20 doesn't like buster. 18 is the highest version.

Tried with 18 and it updated and got working.
