Trying to use the option

--unregister — Use this parameter when uninstalling a cluster to unregister the cluster and release license from Mission Control.

but i received

# ./dynatrace-managed.sh --unregister
Starting Dynatrace 1.166.90.20190423-100415 installer ...

Upgrade failed after less then 1 second.
Exit code: 1

Errors:
You cannot use "--unregister" option during upgrade.

More details in log file: "/var/log/dynatrace/install.log"

I've stopped the server, disabled automatic updates and getting the same. How can I cancel Upgrade?

Hello Daniel,

I don't think you can use that option by itself. Try: /bin/sh dynatrace-managed.sh --uninstall --unregister

Thanks,
