Cannot install Collections package. Not found

[shapesim]

I get this error on 2019.3. It seems to only happen to this Collection package

Issue is this: Online staging packages directly no longer available from browsers.

Solution is to edit the Packages/manifest.json, changing:

“registry”: “https://staging-packages.unity.com”

to

“registry”: “https://packages.unity.com”
