Well I don&#x27;t know what I&#x27;m doing wrong.<p><pre><code>    $ .&#x2F;skod -s &quot;mirrors.digipower.vn&quot; --download &quot;&#x2F;centos&#x2F;RPM-GPG-KEY-CentOS-7&quot;
    :: Error Failed to get &#x27;&#x2F;centos&#x2F;RPM-GPG-KEY-CentOS-7&#x27; size.
</code></pre>
This works:<p><pre><code>    $ curl ftp:&#x2F;&#x2F;mirrors.digipower.vn&#x2F;centos&#x2F;RPM-GPG-KEY-CentOS-7</code></pre>
