Syntax error openHAB-wrapper

I am expecting a startup error on the raspberry with openhab2.

/opt/openhab2/runtime/karaf/bin/openHAB-wrapper: 1: /opt/openhab2/runtime/karaf/bin/openHAB-wrapper: Syntax error: "(" unexpected

I installed the service via openhab console:install-service.

Other than that, if I start openhab via ‘’, I am getting a
HTTP ERROR 404 Problem accessing /start/index. Reason: Not FoundPowered by Jetty://

The install-service does not work on a Raspberry Pi, see
