body: <p>For some time, when trying to run dbus gives me the following error, even if I'm logged in as root:</p>

  <p>I tried to delete this file as root via the rm command, but displays the same error.
  I have installed : </p>

  <p>Command "dmesg | grep dbus" nothing displays. Reinstalling dbus also in no way helped. Thanks for any help</p>
