title: Installing snmp-mibs-downloader on debian 10 buster
body: <p>I have installed net-snmp on a linux machine with debian 10 buster and now I need to install snmp-mibs-downloader.</p>
  <p>Although I have previously run</p>
  <pre><code>sudo apt-get update
  </code></pre>
  <p>when executing:</p>
  <pre><code>sudo apt-get install snmp-mibs-downloader
  </code></pre>
  <p>displays the following screen output, indicating that it cannot find the requested packet:</p>
  <pre><code>Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  Package snmp-mibs-downloader is not available, but is referred to by another package.
  This may mean that the package is missing, has been obsoleted, or
  is only available from another source
  
  E: Package 'snmp-mibs-downloader' has no installation candidate
  </code></pre>
  <p>I have seen on the internet that this could be solved by editing the file</p>
  <pre><code>/etc/apt/sources.list.d/nonfree.list
  </code></pre>
  <p>But it does not explain what should be written in it.</p>
  <p>Any help that allows me to install snmp-mibs-downloader is appreciated.</p>
