User story

I want to run L4D2 server through LinuxGSM.

Game

Left 4 Dead 2

Linux distro

Debian 12

Command

command: install

Further information

Hi.
I've used to run l4d2 instances on other Debian 12 machines with LinuxGSM many times, but now I'm not allowed to run it anymore, not even running it manually with steamcmd

    Exact same issue. I had a server years ago on Ubuntu but I grabbed an old box and have been trying with Debian 12 with the same results.
