title: pecl could not create lock file
body: <p>I have problems with pecl (ubuntu 20 / xampp 8.0.1), when trying to install something I get the following message:</p>
  <blockquote>

  .....................done: 96,583 bytes
  ERROR: failed to mkdir /opt/lampp/lib/php/test/apcu/tests</p>
  </blockquote>
  <p>When i try the suggested channel update command I get:</p>
  <blockquote>
  <p>could not create lock file</p>
  </blockquote>
  <p>When trying to do pecl upgrade-all I get</p>
  <blockquote>
  <p>pear.php.net is using a unsupported protocol - This should never happen.</p>
  </blockquote>
  <p>Unfortunately I couldn't find anything helpful yet. I'd really appreciate any suggestions how to solve this problem.</p>
