title: "Microsoft NuGet - Package installation failed" error while installing Visual Studio 2013
body: <p>I attempted to repair my existing install of Visual Studio 2013 today (I installed it last night and got an unknown error, followed by a ton of package errors on launch) and was greeted with this message: <img src="https://i.stack.imgur.com/2vFVE.png" alt="error message"></p>
  
  <p>Googling didn't reveal anything, so I thought I would ask here. <a href="https://dl.dropboxusercontent.com/u/202386712/vslogs.cab" rel="noreferrer">Here are the logfiles</a> I got with the log collector <a href="http://support.microsoft.com/kb/2899270#furtherhelp" rel="noreferrer">as discussed here</a>.</p>
  
  <p>Can anyone tell me what's going on?</p>
