Hello @Jagadeesh_aditya, welcome to the forum.

It looks like you are using the right installation command

```auto
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered) --node18

```

If you try again after a short wait it might work.  
Otherwise, does your Raspberry Pi have access to the internet - does `sudo apt update && sudo apt -y full-upgrade` give any errors?

Are you trying to install over a university network?

sudo apt update gives the following

and sudo apt -y full-upgrade also giving lot of errors.

I am using my mobile hotspot and accessing the raspberry pi desktop through VNC viewer

Why? You would have much less troubles if you access it via SSH (far less computationally expensive than running VNC)

I dont think you ran the command @jbudd suggested. If you look at it, it has `--node18` on the end, but you are seeing errors for node 20.

Before moving on to the below, I suggest you try the bash script once more, with the `--node18` as JBudd posted.

### Manual install:

lastly, that error is pretty well covered around the internet & most recommend you head to the nodejs repository where install instructions have improved somewhat lately: [GitHub - nodesource/distributions: NodeSource Node.js Binary Distributions](https://github.com/nodesource/distributions#installation-instructions)
