I configured everything as said in the readme. I'm running on an ubuntu server installation

Looks to me like there is something wrong with your configuration file.
Normally sed would set some settings in SpaceEngineers-Dedicated.cfg.
Maybe you started the container without placing the appropriate configuration file beforehand?
