=== NPM Update fails ===
https://github.com/npm/cli/issues/3257

The root cause for many is a connection problem, due to wifi failure, ipv6 enabled, but no routing, dns failure, http proxy or tls certificate checking failure.
 
 npm set strict-ssl false
 npm config delete proxy
 .npmrc
 yarn.lock
 node --dns-result-order=ipv4first /usr/bin/npm
