[slothymc]

Hi! I'm trying to install Forge 1.18.2 build 40.1.80 on a linux machine runnign pterodactyl. The startup command is the following:

Spoiler

java @user_jvm_args.txt @libraries/net/minecraftforge/forge/1.18.2-40.1.80/unix_args.txt "$@"

But when I try to start the server, I get this error message:

EDIT: installer log: https://snippet.host/osrvcs

added installer log

In case it's neccesary, here is an image with the files

If the installer log you posted is the complete file, it looks like your install didn't complete properly.

There should be a message at the bottom of the file saying it finished.

Try reinstalling and make sure it tells you it completed successfully.
