title: How to fix ERROR 1726 (HY000): Storage engine 'MyISAM' does not support system tables. in Mysql 8.0 after CREATE USER
body: <p>I have an installation of <strong>Debian Stretch</strong> and a new installation of <strong>Mysql 8.0</strong> (no changes in configuration yet). When I try to create a new user with:</p>
  
  <pre><code>mysql&gt; CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'xyz';
  </code></pre>
  
  <p>I got the following:</p>
  
  <blockquote>
    <p>ERROR 1726 (HY000): Storage engine 'MyISAM' does not support system
    tables. [mysql.db]</p>
  </blockquote>
  
  <p>Any suggestion about what the problem could be?</p>
  
  <p>Thank you</p>
