HI @fogmajor

This requirement was set in V10, so you will need to update your Node JS Version to the latest supported by Node RED (and to follow up on any needed rebuilds for Native Nodes)

 ![Screenshot 2026-04-09 at 17.45.24](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/8/2/82b18a39051e9982dee099ecc44fa32bbc8c7c53.png)

But I do suggest to STOP! and read some more before continuing, as V11 contains significant breaking changes.

Hello again Marcus  
Thank you for your prompt response and for your work on the zwave palette

Are there limitations on installing version 11  
Below is my current setup

OS - Ubuntu 24.04.4 LTS  
Node-red version - 4.1.8  
Node.js version 18.19.1

Thanks in advance

Andrew

Hi @fogmajor,

There aren’t any strict _limitations_ with installing v11 — but there are definitely some changes (all for the better 😄).

If you take a look at the linked topic, it should give you a solid overview of what’s changed and how to adapt. The biggest updates are around the UI and the message format. In return, you get a much more robust and future-proof framework, which also helps me keep everything aligned with the rapid development happening in the underlying library.

That said, you _will_ still need to upgrade NodeJS to really benefit from the newer version.

Let me know if you hit any issues during the upgrade 👍

**Side Note** : Anything wrong with V11 - I do depend on user feedback to be made aware of the shortcomings, so I can address them 😃

I'm away this weekend : A way overdue visit to the north of the country I reside starts tomorrow morning to visit family.

Hi Andrew.

Node RED is already updated, it's Node JS you need to update (and follow up on rebuilds)

I think @TotallyInformation / @dceejay (+ many other of the admin team) has ways - Im a little rusty on how to update NodeJS alone.

Once you update NodeJS (not Node RED) - you should be set to update the Node

**EDIT**  
Or @Steve-Mcl😃

Since you are running on Ubuntu - the sensible way to install (and update) Node-RED and Node-JS is via the [official installer script](https://nodered.org/docs/getting-started/raspberrypi).

e.g.

```auto
bash <(curl -sL https://github.com/node-red/linux-installers/releases/latest/download/update-nodejs-and-nodered-deb) --node22

```

I think that reads from your OS's configured repository - which might not be fully current, use Steve's approach

You should try  
`apt update`  
followed by  
`apt upgrade`  
to update Unbunto to latest libraries

I use `nodesource` for Node JS installs/updates - not sure if thats right or wrong, but seems todo magic

If you use the script then you may want to add —node22 (or whichever version is required) to the command to force it to that version

The best thing you can do with any big tool is check if it has its own install and management tooling. Node.js certainly does. There are installers for Debian, Ubuntu and many other OS's. A 3rd party maintains apt repo's and that is the best approach.

Try this:

```auto
curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
sudo apt install -y nodejs

```

> [@fogmajor](#):

> Marcus i thought sudo apt-get install nodejs was the way  
> Will research

You are correct. But the trick is to get the correct repo that maintains more up-to-date versions than the OS's defaults.
