This is my first time setting up a minecraft server, and I had wanted to add modding capabilities with forge but I keep getting errors while installing?

I have tried installing several versions of forge but i have ended up getting unable to find class and checksum errors?

Same thing when trying yay -S forge-server

The only thing that works is installing the vanilla minecraft server from minecraft itself?

Found a similar post from 3 weeks ago as the only similar issue, seems specific to some linux distributions, like cachyos which i am using, due to libzng processing hashes differently? https://github.com/PrismLauncher/PrismLauncher/issues/3889
