# SteamCMD in LXC — Two Key Issues and Fixes

## Issue 1: "Failed to install app (Missing configuration)"

**Cause:** SteamCMD inside LXC does not auto-detect platform.

**Fix:** Add `+@sSteamCmdForcePlatformType linux` before the login command in the SteamCMD invocation.

```bash
steamcmd +@sSteamCmdForcePlatformType linux +login anonymous +app_update 2394010 +quit
```

## Issue 2: DNS Resolution Failures Inside LXC

**Cause:** Using 8.8.8.8 as nameserver inside LXC caused resolution failures.

**Fix:** Switch to local gateway/Pi-hole:
```bash
pct set 230 --nameserver 10.10.0.1
# then reboot the container
```

## Bonus: Locale Fix
SteamCMD may complain about locale. Fix:
```bash
sed -i 's/# en_US.UTF-8/en_US.UTF-8/' /etc/locale.gen
locale-gen
```

## Behavior Note
SteamCMD frequently disconnects with "No Connection" during large downloads but recovers automatically — this is normal, not a blocking error.
