Manage palette not available

[Bickes]

Hi,
I tried to install a new node in node red. Unfortunately the "Manage palette" is not available in the menu.
A Google search told me, that it could be due to an older version of npm.

I´ve done already an updat with:
sudo apt update
sudo apt upgrade

How do I update npm in Openplotter without causing trouble?

sudo npm install -g npm@latest

Hola Sailoog, moltes gràcies!
Unfortunaltely that didn´t help.  There´s a long error message. 

Code:

xx@xx:~ $ sudo npm install -g npm@latest
/usr/lib/node_modules/npm/lib/cli.js:35
    throw err
    ^
