title: The "metadata.json" file for the box 'laravel/homestead' was not found
body: <p>OC: Windows 10.
  Vagrant: 2.2.1.</p>
  
  <p>I run:</p>
  
  <p><code>vagrant box add laravel/homestead --provider virtualbox</code></p>
  
  <p>and got an error:</p>
  
  <pre><code>==&gt; box: Loading metadata for box 'laravel/homestead'
      box: URL: https://vagrantcloud.com/laravel/homestead
  ==&gt; box: Adding box 'laravel/homestead' (v6.4.0) for provider: virtualbox
  The "metadata.json" file for the box 'laravel/homestead' was not found.
  Boxes require this file in order for Vagrant to determine the
  provider it was made for. If you made the box, please add a
  "metadata.json" file to it. If someone else made the box, please
  notify the box creator that the box is corrupt. Documentation for
  box file format can be found at the URL below:

  </code></pre>

  <p>Before that, I had already executed this command, I added the box and everything worked for me, but then I decided to remove the box through <code>vagrant box remove laravel/homestead</code> and add it again.</p>
