Been a while experiencing an issue - Turnkey Linux and Inf Skyblock

So I’m attempting to setup a server, as it’s been a very long time since I’ve run it, and I’m encountering the attached error when attempting to manually start the server.

What am I missing, probably something stupid I’m sure.

Though it may not be directly responsible for the exact error you’re seeing, you shouldn’t be running commands as root, when the servers themselves are meant to be run explicitly by non-root users. Permissions issues could exist, in general.

That said, have you googled your error in terms of infinite sky block and seen any similar errors?

Next question: are you sure that all the files that FTB requires are present in the server’s directory? Such as the vanilla jar and the -universal jar?
