Before I start the upgrade script:
> tiby007@tiby007-desktop:~$ node -v
> v10.19.0
> tiby007@tiby007-desktop:~$ npm -v
> 6.14.4
After running this upgrade script
```auto
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
```
I get the following fault always:

It should but since you are on a Raspberry Pi it would be better if you had [Raspberry Pi OS](https://www.raspberrypi.com/software/operating-systems/)
With Ubuntu, especially if its the 64bit, you may have some 'hiccups' with hardware compatibility (i could be wrong)

As it is now .. what do you get when you run
```auto
curl -fsSL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt-get install -y nodejs
```

Yes. I have Node-RED running on Ubuntu 20.04 running in a VM on a Windows machine - so NOT on a Pi but the version of Linux is not the problem

What does this command show?
`sudo apt policy nodejs`
and paste the result from
`sudo apt remove nodejs npm`
and then run
`sudo apt policy nodejs`
again.
**[Edit]** Sorry, just realised I replied to @Buckskin, the question was meant for @tiby007

I have just remembered the main cause of a similar problem recently. In addition to the above what do you see if you run
`sudo apt update`

I removed the SD card to check the type, then inserted back and it's damaged. Nothing can read it. It is even not recognised neither on my Rasberry or on my computer or on my girlfriend computer. Everything is gone -\_\_\_\_\_\_-
BUT, I bought a new SD card, put the Rasberry OS on it and noticed, that it has a built in NODE-RED. At the first time it worked well, I could control my GPIO pins through Node-RED, but now it says, GPIO is not available. I feel it's another topic, so thank you all your effort! Unfortunatelly, we won't know why the UBUNTU didn't want to accept the upgrade of the Node-RED...

Use the install script from the node red docs to update it.
