title: SSL Error while installing any package from conda prompt
body: <p>I use Anaconda Navigator for my machine learning experiments. Recently, I have started getting this strange SSL error no matter what I try to install using conda prompt. The error is SSL error. I am posting the error message that I get</p>

  <p>I have an institutional proxy server; the credentials, apt.conf file etc are all OK.</p>
  
  <p>Even then I am not able to install any package using conda.</p>
  
  <p>Interestingly, I have installed numerous packages using conda prompt and I never faced any such error until recently. Also, I am able to follow the links (using the browser) given in the error message which means that the proxy is not blocking the site. </p>
  
  <p>I was asked to use</p>
  
  <pre><code>conda config --set ssl_verify True
  </code></pre>
  
  <p>but even this did not help. Any help ?</p>
  
  <p>I even entered the proxy server details as given in <a href="https://stackoverflow.com/questions/48354258/http-error-while-using-conda-for-installation-of-any-packages">HTTP error while using conda for installation of any packages</a></p>
