Hi, I got the following Error Message from the PackageKit today: "A security policy in place prevents this sender from sending this message to this recipient, see message bus configuration file (rejected message had interface "org.freedesktop.PackageKit.Transaction" member "Cancel" error name "(unset)" destination "org.freedesktop.PackageKit")" What shall I do to solve it? Which configuration file is meant? /etc/dbus-1/: -rw-r--r-- 1 root root 2524 5. Dez 21:14 session.conf drwxr-xr-x 2 root root 4096 5. Dez 21:14 session.d -rw-r--r-- 1 root root 3368 5.
