Cannot add any package after adding private registry within an empty environment

[sairus7]

If I add a private registry (]registry add ...) to a fresh system with a completely empty environment with no packages installed, then Julia cannot install any other public or private packages - it just says Cannot find name corresponding to UUID
To fix this, I need to remove private registry, then install any public package to General registry (e.g. ]add ArgParse), then add private registry again, and then it works fine.

The easiest solution is to do ]registry add General ... to install both General and your own registry at the same time.
There's not so much LocalRegistry can do about this except possibly mention it somewhere in the documentation.
