[WeaselScience]

Same problem here, but on my Lubuntu 18.04.5, it seems to install nodejs from ubuntu's repositories, completely ignoring repositories set up by nodesource.

Output:

gartraukis@gartraukis:~$ curl -fsSL https://deb.nodesource.com/setup_16.x | sudo -E bash -

Can confirm. Only node gets upgraded (v14 -> v16), npm stays the old version (v6) not the bundled one (v8).

[TimDaub]

can confirm and then additionally when I use the command to install n v18, I end up with v12 on Ubuntu 22

When this problem happens there is usually an error in your environment which causes our package not to be installed. Can you give us more information?
