ok, the issue you encounter is that the RAUC service is not running on your system and that the RAUC client, i.e. your command line tool, does not correctly start it via dbus activation.

The bug that causes this issue is located in the D-Bus service file `de.pengutronix.rauc.service` and shows that we haven't used non-systemd systems for a long time...
Am I right in assuming you are using a non-systemd-based system?

The reason why activation is not working for the non-systemd case is that the `Exec` argument in the dbus service file lacks the required `service` argument for RAUC in order to be started properly as the background service. Thus the fix is:

--- a/data/de.pengutronix.rauc.service.in
+++ b/data/de.pengutronix.rauc.service.in
@@ -1,5 +1,5 @@
 [D-BUS Service]
 Name=de.pengutronix.rauc
-Exec=@bindir@/rauc
+Exec=@bindir@/rauc service
 User=root
 SystemdService=rauc.service


Many thanks for revealing this issue! I've created a PullRequest on GitHub for this:

https://github.com/rauc/rauc/pull/104


Does this solve your problems?


Best regards

Enrico
