  </code></pre>
  
  <p>I have tried various solutions. I installed python3.7 and then tried but same.
  I also tried this but the result was also same.</p>
  
  <pre><code>$ sudo apt-get install python3-setuptools ca-certificates
  </code></pre>
  
  <p>and same thing happens when I install django in a venv. Same goes for the installing a specific version of django.</p>
