+# P0-007: Install Script Template Uses Wrong Path Variables
+
+**Priority:** P0 (Critical)
+**Date Identified:** 2025-12-17
+**Status:** ✅ FIXED
+**Date Fixed:** 2025-12-17
+**Fixed By:** Casey & Claude
+
+## Problem Description
+
+The Linux install script template uses incorrect template variable names for the new nested directory structure, causing permission commands to fail on fresh installations.
+
+**Error Message:**
+```
+chown: cannot access '/etc/redflag/config.json': No such file or directory
+```
+
+**Root Cause:**
+- Template defines `AgentConfigDir: "/etc/redflag/agent"` (new nested path)
+- But uses `{{.ConfigDir}}` (old flat path) in permission commands
+- Config is created at `/etc/redflag/agent/config.json` but script tries to chown `/etc/redflag/config.json`
+
+## Files Modified
+
+- `aggregator-server/internal/services/templates/install/scripts/linux.sh.tmpl`
+  - Line 310: `{{.ConfigDir}}` → `{{.AgentConfigDir}}`
+  - Line 311: `{{.ConfigDir}}` → `{{.AgentConfigDir}}`
+  - Line 312: `{{.ConfigDir}}` → `{{.AgentConfigDir}}`
+  - Line 315: `{{.LogDir}}` → `{{.AgentLogDir}}`
+
+## Verification
+
+After fix, fresh install should complete without "cannot access file" errors.
+
+## Impact
+
+- **Fixed:** Fresh installations will now complete successfully
+- **Why P0:** Blocks ALL new agent installations
+- **Status:** Resolved
