title: Visual Studio Code update on Ubuntu
body: <p>After starting Visual Studio Code I got message in top of window saying </p>
  
  <blockquote>
    <p>There is an available update.</p>
  </blockquote>
  
  <p>and link to download. So I downloaded <code>code-stable-code_1.21.0-1520420608_amd64.tar.gz</code> file and don't have slightest idea what to do with it next. </p>
  
  <p>What should I do to update it?</p>
