Please provide content log to LinuxGSM developers https://linuxgsm.com/steamcmd-error.

Start with the sdtdserver install entry point and trace the SteamCMD invocation for app 294420 on Ubuntu 24.04. Reproduce the reported install command and inspect how the “Missing configuration” result is handled; done means the 7 Days to Die server files install and setup completes without the error.
