title: centos 7.3 docker-engine conflicts with docker-common-2
body: <p>After following the official installation document below
  <a href="https://docs.docker.com/engine/installation/linux/centos/" rel="nofollow noreferrer">https://docs.docker.com/engine/installation/linux/centos/</a></p>
  
  <p>I still end up with failure with docker-common-2 transaction conflict</p>
  
  <blockquote>
    <p>Transaction check error:
      file /usr/bin/docker from install of docker-engine-1.13.0-1.el7.centos.x86_64 conflicts with file from package docker-common-2:1.10.3-59.el7.centos.x86_64</p>
  </blockquote>
  
  <p>I tried <code>yum remove docker-common-2</code> immediately but apparently there is no such package found so I <code>yum clean all</code> but the failure is still there.
  I had encountered that selinux conflict before and I did remove conflict the package docker-selinux if it is the case.</p>
  
  <p>How can I solve this? </p>
