Repro steps

• Add dependency on a private repo such as FontAwesome 5 Pro
• Run ng update @angular/core

Observed behavior

Not found : @fortawesome/pro-regular-svg-icons

Mention any other details that might be useful (optional)

This works fine using npm directly because the private repo has already been registered with npm

There is definitely a problem when using a private npm repository. I could only run ng update correctly once I removed my .npmrc file, and removed every private package from package.json. After running ng update @angular/cli' it finally correctly generated the angular.json file and I readded all the references I removed before.

@hansl & @filipesilva This thread still has the “need more info” and “low frequency” labels. Based on the thread’s activity, I assume that both are not valid anymore and possibly give a false impression of the severity of this issue.
