Linux 32bit and nodejs
It looks like nodejs does not officially support 32 bit installs after version 8. The package binaries for x86 in the repo are blank for all ubuntu distributions. Any 32 bit ubuntu (maybe all linux?) install should go through the unofficial procedure detailed in the Raspberry Pi 1 and Zero method with the modification below:

install node and npm
sudo curl -Lf# "https://unofficial-builds.nodejs.org/download/release/v14.17.4/node-v14.17.4-linux-x86.tar.gz" | sudo tar xzf - -C /usr/local --strip-components=1 --no-same-owner
