I’m confused by the fact that you say you want to upload something, yet then describe a command that is intended to change the build process. Ordinarily, the place you serve a PWA from is not the same place you build it.
So, let’s say alice is the name of the host you are using for your development work on, and barbara is the host where your PWA will be deployed from.
The first question is “are you trying to run that ng add command on alice or barbara?”. If alice, then personally I would recommend introducing alice to Linux. Presumably you’re not going to be particularly responsive to that suggestion, so I guess you’ll need to wade through that Microsoft documentation that is included in your error message. It looks pretty comprehensive and relevant to your situation.
If you’re trying to run ng add on barbara, that’s weird. I would recommend not doing that, and instead running all build-related commands on alice instead. I suppose this advice applies as well in the case where alice and barbara are the same machine: separate them and concentrate on the build environment, not the hosting environment.
