do you do recent development on morty? This *very* old now. Don't you have to option to switch to a recent release? > # dbus-send --system --dest=de.pengutronix.rauc --type=method_call --print- > reply /de/pengutronix/rauc de.pengutronix.rauc.GetSlotStatusError > org.freedesktop.DBus.Error.UnknownMethod: No such interface > 'de.pengutronix.rauc' on object at path /de/pengutronix/rauc The proper call would be: dbus-send --system --dest=de.pengutronix.rauc --type=method_call --print- reply / de.pengutronix.rauc.Installer.GetSlotStatus So, the issue is that the object path in RAUC is only "/", which is possible but actually not the convention for D-Bus interfaces and does not allow versioned interfaces, etc. In the documentation we have some examples using the D-Bus API with 'busctl': https://rauc.readthedocs.io/en/latest/using.html#using-the-d-bus-api Hope that helps?
