title: Not able to install python3 on Redhat 8 offline mode
body: <p>I created an offline repo for RHEL 8:</p>
  <ul>
  <li>downloaded all needed packages with <code>dnf download</code></li>
  <li>create repodata with <code>createrepo</code> command</li>
  </ul>
  <p>I'm able to install most of the packages in offline mode but python3 can't be installed
  The error I'm receiving is:</p>
  <pre><code>No available modular metadata for modular package 'python36-3.6.8-2.module+el8.1.0+3334+5cb623d7.x86_64', it cannot be installed on the system
  Error: No available modular metadata for modular package
  </code></pre>
  <p>What can I do to fix this?</p>
  <p>Regards,</p>
