Error: "org.freedesktop.DBus.Error.UnknownMethod: Method "CreateDevice" with signature "s" on interface "org.bluez.input.Manager" doesn't exist" probably means that you haven't installed the bluez-input package.
This has fixed it for me: quit kbluetooth4 sudo apt-get install bluez-input sudo invoke-rc.d bluetooth restart start kbluetooth4 and try adding you mouse kdebluetooth and gnome-bluetooth should both depend on bluez-input, or at least detect whether it is installed and -- if necessary -- at least prompt the user to install it manually. -- kbluetooth4 fails to add mouse https://bugs.launchpad.net/bugs/268383 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
