Hello from 2015! Since this bug is still open I thought it might help if I post how I resolved the error on my Ubuntu 12.04 LTS headless server:
apt-get install python-gobject policykit-1 Edit XML configuration file /etc/dbus-1/system.d/com.ubuntu.ComputerJanitor.conf and add following line as a child of the <policy context="default"> element: <allow send_destination="com.ubuntu.ComputerJanitor"/> It should look like this <!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd";> <busconfig> <policy user="root"> <allow own="com.ubuntu.ComputerJanitor"/> </policy> <policy context="default"> <allow send_interface="com.ubuntu.ComputerJanitor"/> <allow receive_interface="com.ubuntu.ComputerJanitor" receive_sender="com.ubuntu.ComputerJanitor"/> <allow send_destination="com.ubuntu.ComputerJanitor"/> </policy> </busconfig> -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/715707 Title: Error:dbus.proxies:Introspect error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/computer-janitor/+bug/715707/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
