title: Anaconda Safety Error: Skip sha256 mismatch and continue
body: <p>I get the following error when trying to install setuptools 39.1.0 which is required for upgrading anaconda</p>
  
  <pre><code>SafetyError: The package for setuptools located at F:\Python\Anaconda3\pkgs\setuptools-39.1.0-py36_0
  appears to be corrupted. The path 'Scripts/easy_install.exe'
  has a sha256 mismatch.
    reported sha256: 993203a406e04936a07829b1f482fd27d739b640482e213f4c49ea1ee78a5fcf
    actual sha256: ea8a03c54607998725927caa8e1babd997f0353b6d1ee35a28b154db689642ce
  </code></pre>
  
  <p>I tried with <code>-f</code> flag attempting to bypass, but it did not work.</p>
  
  <p>Even weird, when I manually tried to update setuptools, it was successfully updated to <code>39.2.0</code>, but unfortunately when I update anaconda, conda wants to downgrade it to <code>39.1.0</code> :/</p>
  
  <p>What do I do to install it anyway? Or should I install setuptools from elsewhere?</p>
