title: Visual Studio for Mac does not get past "Add packages"
body: <p>I am trying out Xamarin Forms on Visual Studio for Mac.</p>
  
  <p>When I create a new project, I see VS is trying to add packages to the solution, but every single time- it fails at the same place...</p>
  
  <p>Here is the Package Console output:</p>

  <p>On this new project, after the package installer fails, it always fails to build with the default assets:<a href="https://i.stack.imgur.com/Anhvo.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Anhvo.png" alt="styles.xml"></a></p>
  
  <p>Is it possible other dev environments are affecting Visual Studio?</p>
  
  <p>Is there a more stable way I can use Xamarin forms on a Mac?</p>
  
  <p>Thanks in advance!</p>
