Need help creating custom modpack server

[deadmaneatin]

I've recently made a modpack, which I tried to follow the tutorial exactly. It works on single player, so I've tried to create a server (I'm using linux to host it). I dragged the jar out, and made a start.sh with the appropriate commands to start it with. Each time I get the following error:

You deleted a file you aren't supposed to delete. Make a new Forge server (By putting forge universal from http://files.minecraftforge.net/ into the original minecraft server package)
