Bug fix targetted for 14.04</p> <p>I opened a bug at <a href="https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/1252821">bugs.launchpad.net</a> following discussion <a href="https://lists.ubuntu.com/archives/apparmor/2013-November/004681.html">here</a> with Tyler Hicks:</p> <blockquote> <p>The AppArmor mediation code only has the ability to check peer labels over UNIX domain sockets. It is most likely seeing an error when getting the label and then refusing the connection.</p> </blockquote> <p>Note: the disable flag is not recognized by dbus < 1.6.12, so you need to package different versions of mydaemon.conf depending on systen), else dbus-daemon will fail on launch if no apparmor... I used for now in my CMakeLists.txt :</p> <pre><code>IF(EXISTS "/usr/sbin/apparmor_status") install(FILES dbus_daemon-apparmordisabled.conf RENAME dbus_daemon.conf DESTINATION /etc/dbus-1/ ) ELSE (EXISTS "/usr/sbin/apparmor_status") install(FILES dbus_daemon.conf DESTINATION /etc/dbus-1/ ) ENDIF(EXISTS "/usr/sbin/apparmor_status") </code></pre>
