title: how to enable repo with yum-config-manager --enable<repo>
body: <p>During the try to install yum-utils, I ran into the problem that there seems to be no enabled repos. How can I enable <code>yum-config-manager</code>, when I seem to need him to do so.</p>
  <pre><code>[root@spectrumscale ~]# yum install yum-utils
  Failed to set locale, defaulting to C

  There are no enabled repos.
  Run &quot;yum repolist all&quot; to see the repos you have.
  You can enable repos with yum-config-manager --enable &lt;repo&gt;
