Still no solutions?

Do not install npm using apt. If you are installing nodejs from nodesource, then you always have npm available and should npm i -g npm@latest (perhaps with sudo) to get the latest npm client.

Solution: just run

sudo apt install nodejs

and npm will be installed automatically; do not apt install npm separately, which was my mistake.
