title: Xcode 8 beta 2 installation error
body: <p>I've downloaded Xcode 8, Beta 2 several times and attempted to install it. Each time, I've encountered the following error when attempting to decompress the file:</p>
  
  <p><code>The operation couldn't be completed. cpio read error: Undefined error: 0</code></p>
  
  <p><strong>What I've tried:</strong></p>
  
  <ol>
  <li><p>Googling suggested I might have a space issue, so I went medieval on my hard drive and cleared out 40 gigs. The file is a fraction of that, even uncompressed.</p></li>
  <li><p>I ran Onyx and cleaned everything, ran maintenance scripts, repaired permissions, etc.</p></li>
  <li><p>Multiple downloads, thinking perhaps a download might have been corrupted.</p></li>
  </ol>
  
  <p>Any other suggestions re: what might get this thing working?</p>
