Vagrant search box ubuntu/groovy64 sends you to a 404 Not found page

404 Not Found

Sorry, the page /ubuntu/boxes/groovy64 could not be found.

This error could mean one of three things:

The resource doesn't exist
The resource exists, but requires proper authorization to access
The resource exists, but its owner organization is delinquent

If someone has linked you to this resource, ensure that they have given you proper permissions to access it.
