  <p>In case the image is not clear the error says </p>
  
  <pre><code>System.IO.IOException: The authentication or decryption has failed. ---&gt; System.IO.IOException: The authentication or decryption has failed. ---&gt; Mono.Security.Protocol.Tls.TlsException: The authentication or decryption has failed.
  </code></pre>
  
  <p>Anybody facing this issue and have a solution? I cannot continue installation of aspnet packages unless this is fixed and I wasn't able to get any solution from my online searches. Additional info, when i run 'sudo mozroots --import --sync' I get the error</p>
