Hosting FiveM server on a Dedicated machine

Hi guys, im trying to setup a FiveM server on my dedicated machine running Ubuntu 16.04.
I have done everything for the setup but when i start using the .sh script i get this error:
“2017-05-02 19:21:20.5009|FATAL|CitizenMP.Server|Could not open the configuration file citmp-server.yml.”

And when i type the mono command in the folder it seems like the server starts but then i get this error:
Error was to long to paste here ^
