We can improve the documentation to say something like

but I don't know if we should go into details on how to do it on each OS.

Googling for "ubuntu /usr/bin/env: ‘node’: No such file or directory" 
gives some helpful answers - including https://askubuntu.com/a/1053068

This stacktrace shows Python catching that license-checker failed. Was 
there any output before this, after "Generating LICENSES.txt"?

I guess this perhaps could be caused by partial installation from 
previous attempts. Try to delete kallithea/front-end/node_modules/ and 
try again.
