Crash while starting new Forge Server on Linux

[Adrieldf]

So, I'm trying to create a 1.12 forge server on a azure linux virtual machine, but it crashes right in the beggining. Here's the error message:

If I run the vanilla .jar it works normally, but forge doesn't, anyone ever came across this error before?

 

Edit: If I try to run the forge.jar on Windows the server works normally, but on the linux server via terminal it doesn't work.
