title: Error: gpg: no valid OpenPGP data found while installing Filezilla
body: <p>Here I am trying to install Filezilla in ubuntu 16.04. The commands which I use are:</p>
  
  <ol>
  <li><code>sudo sh -c 'echo "deb http://archive.getdeb.net/ubuntu xenial-getdeb apps" &gt;&gt; /etc/apt/sources.list.d/getdeb.list'</code></li>
  <li><code>wget -q -O- http://archive.getdeb.net/getdeb-archive.key | sudo apt-key add -</code></li>
  <li><code>sudo apt update &amp;&amp; sudo apt install filezilla</code></li>
  </ol>
  
  <p>But when I try the second command I am getting an error </p>
  
  <blockquote>
    <p>gpg: "no valid OpenPGP data found"</p>
  </blockquote>
  
  <p>Can anyone tell me how to overcome this error? Thanks in advance. </p>
