title: Cannot Perform apt update on Parrot OS
body: <p>In last two days I have installed Parrot Mate and then upgraded it to latest
  I will specify the introduction to my problem</p>
  <p>The version of my OS is as follows:</p>
  <pre><code>Linux parrot 5.10.0-5parrot1-amd64 #1 SMP Debian 5.10.24-5parrot1 (2021-03-20) x86_64 GNU/Linux
  </code></pre>
  <p>Initially I had installed the MATE version but afterwards I also installed the KDE desktop Environment using apt.</p>
  <p>After this whenever I perform <strong>sudo apt update</strong> I get the following error.</p>
  <pre><code>

  <p>My /etc/apt/sources.list.d/parrot.list contains the following lines</p>
  <pre><code># parrot repository

  <p>Because of the error I also tried <strong>sudo parrot-upgrade</strong>
  but again the output was same</p>
  <p>Any help please, Thank you: :)</p>
