title: Unable to remove php7.2-fpm from Ubuntu on boot
body: <p>I would like to remove <code>php7.2-fpm</code> from on boot start because <code>Supervisor</code> process manager will take care of starting <code>php7.2-fpm</code>. Do do this I had tried following commands but none of them worked for me. Ubuntu version is <code>14.04</code>.</p>
  
  <pre><code>&gt; sudo update-rc.d php7.2-fpm remove
      Output: update-rc.d: /etc/init.d/php7.2-fpm exists during rc.d purge (use -f to force)
  
  &gt; sudo update-rc.d -f php7.2-fpm remove
      Output: Removing any system startup links for /etc/init.d/php7.2-fpm ...
  
  &gt; sudo update-rc.d php7.2-fpm disable
      Output: update-rc.d: warning:  start runlevel arguments (none) do not match php7.2-fpm Default-Start values (2 3 4 5)
