In nowadays (~2020) not make sense to copy/paste big scripts from internet to install the official stable version of a package...
There are a simpler (and reliable) way (comparing with this ugly setpup) to do it for node and npm?
Notes: I am using fresh Ubuntu 18 LTS and need standard LTS packages, but apt install build very very old versions:
node --version= v8.10.0, but "all people" need v12+ as the official recommendation.npm -v= 3.5.2, but "all people" need v6+ as the official recommendation.I try
sudo snap refresh node --channel=13but "snap 'node' is not installed"This answer seems the only good solution
