title: Emacs can't find package to install
body: <p>I got this error when trying install Emacs package automatically.</p>
  
  <pre><code>Warning (initialization): An error occurred while loading `/Users/username/.emacs.d/init.el':
  
  File error: http://melpa.org/packages/projectile-20150619.800.el, Not found
  
  To ensure normal operation, you should investigate and remove the
  cause of the error in your initialization file.  Start Emacs with
  the `--debug-init' option to view a complete error backtrace.
