title: Symfony 4 Sonata User Bundle Installation
body: <p>I followed all instructions from installation guide but still
  have this error during installation of Sonata User Bundle on Symfony 4 application:</p>
  
  <pre><code>Column name `id` referenced for relation from Application\Sonata\UserBundle\Entity\User towards Sonata\UserBundle\Entity\BaseGroup does not exist.
  </code></pre>
  
  <p>My config is totally same as in <a href="https://sonata-project.org/bundles/user/4-x/doc/reference/installation.html" rel="nofollow noreferrer">installation guide</a>.</p>
  
  <p>Didn't find any solutions on stackoverflow or anywhere else.</p>
