Simple as that - when attempting to launch the dedicated server on Ubuntu 18.04, I get the error "Failed to load vanilla resource pack, is the vanilla pack missing from the loaded world?"

It also fails to find server.properties and whitelist.json, which I assume is causing problems.

Pressing return causes the terminal window to return to bash and prints Quit correctly in the window.

Additional note: I tried running the server with sudo and without sudo, both times it fails at the exact same point.
