well, from this log I am not able to get what went wrong. I would need 
the log of the RAUC service in order to give a hint about what went wrong.
Unfortunately, currently there is no way to access the service log from 
the command line client.

Thus, what you can do, if you have set up your system with systemd is 
executing

   journalctl -u rauc.service --no-pager

to get the services log. Alternatively, try to grab the log file from 
your init processes log location or start the service manually on a 
shell where you can get the output from:

   rauc service

Then start the command line interface (i.e. the rauc install ..) from 
another one and you will get the verbose output on the first shell.

Paste your results here and lets see if we can figure out what went wrong.

Yes, this looks right to me, too.

We will try to figured this out when having the logs available
