title: mysqladmin: connect to server at 'localhost' failed
body: <p>Today (2015-05-02) I upgraded my Linux system via apt-get update and<br>
  apt-get upgrade whereas mysql, mysqladmin and a lot more packages<br>
  have been updated. The mysql-server-5.5 runs and I can login and do all<br>
  the typical database operations but when I type:<br></p>
  
  <pre><code>user@ubuntu:~# mysqladmin proc
  </code></pre>
  
  <p>I get the following error:<br></p>
  
  <pre><code>mysqladmin: connect to server at 'localhost' failed
  error: 'Access denied for user 'root'@'localhost' (using password: NO)'
  </code></pre>
  
  <p>Formerly I could solve this issue by simple setting the mysql root password new.<br>
  This does not solve the issue anymore:</p>
  
  <pre><code>user@ubuntu:~# sudo dpkg-reconfigure mysql-server-5.5
  </code></pre>
  
  <p>How do I get the mysqladmin up again without reinstalling mysql?</p>
