title: Failure to update Laravel 5.1 to 5.2 (these conflict with your requirements or minimum-stability)
body: <p>Couple weeks ago I asked this question about trying to upgrade from Laravel 5.1 to 5.2 - <a href="https://stackoverflow.com/questions/38980253/updating-larael-from-5-1-35-to-5-2-fails-to-upgrade-symfony-css-selector">Updating Larael from 5.1.35 to 5.2.* - fails to upgrade symfony/css-selector</a></p>
  
  <p>Although I was given very nice and clear answer, that did not help. As instructed, I have updated <code>"lucadegasperi/oauth2-server-laravel"</code> to <code>"~5.1"</code>, but I still have the same error.</p>
  
  <p>My <code>composer.json</code></p>
