title: dotnet add package bootstrap gives 404 error with source nuget.org
body: <p>I'm trying to add bootstrap to a new dotnet core razor app.</p>
  
  <pre><code>C:\dev\core&gt;dotnet --version
  2.1.302
  </code></pre>
  
  <p>I created the project with the command below and have made any changes yet.</p>
  
  <pre><code>dotnet new razor
  </code></pre>
  
  <p>But now when I try to add the bootstrap nuget package I get the following error.  Is this supposed to work?  The package is present on the nuget website at <a href="https://www.nuget.org/packages/bootstrap/4.1.1" rel="nofollow noreferrer">https://www.nuget.org/packages/bootstrap/4.1.1</a></p>
