title: Installing up-to-date version of Erlang on RHEL7
body: <p>I'm trying to install an up to date (version 20.3 at the moment of the writing) Erlang distribution into RHEL7 (release 7.5 to be exact).</p>
  
  <p>Google tells me the up-to-date Erlang distribution is maintained by <a href="https://www.erlang-solutions.com/" rel="noreferrer">Erlang Solutions</a> at <a href="https://packages.erlang-solutions.com/" rel="noreferrer">https://packages.erlang-solutions.com/</a> (thanks!)</p>
  
  <p>There you also find instructions how to add the repository so that the Erlang can be installed with a package manager:</p>
  
  <blockquote>
    <p>Installation using repository</p>
    
    <ol>
    <li>Adding repository entry</li>
    </ol>
    
    <p>To add Erlang Solutions repository (including our public key for verifying signed package) to your system, call the following commands:</p>
  
  <pre><code>wget https://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm
  rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
  </code></pre>
  </blockquote>
  
  <p>However if I run the commands (I run the rpm command as a root) no Erlang Solutions repo is added to <code>yum repolist</code>. Is RHEL7 different to Centos or are the instructions faulty or what I'm doing wrong ?</p>
  
  <p>The Erlang Solutions repo (and the installation instructions) is referenced also from </p>
