vagrant up - server not starting because a ssh library issue : <p>I get this errormessage:</p>

<blockquote>
  <p>An error occurred in the underlying SSH library that Vagrant uses. The
  error message is shown below. In many cases, errors from this library
  are caused by ssh-agent issues. Try disabling your SSH agent or
  removing some keys and try again.</p>

<p>I've windows 10, vagrant 1.8.5, Oracle VM newest version.</p>

<p>I read a lot about this issue but nothing helps me.</p>

<p>Maybe somebody knows a solution.</p>
