+# DBIS Core Deployment Fixes Applied
+
+## Fixes Implemented
+
+### 1. ✅ Added curl Installation
+**Issue**: `curl` command not found, preventing Node.js installation
+**Fix**: Added explicit curl installation step before Node.js installation in both `deploy-api.sh` and `deploy-frontend.sh`
+
+### 2. ✅ Fixed Node.js Installation Conflict
+**Issue**: Conflict between existing `libnode72` package and Node.js 18 installation
+**Fix**: Added step to remove conflicting packages (`nodejs` and `libnode72`) before installing Node.js 18
+
+### 3. ✅ Fixed File Transfer Mechanism
+**Issue**: `pct push --recursive` flag not supported by Proxmox
+**Fix**: Changed to use `tar` archive creation and `pct push` for single file transfer:
+- Create tar archive: `tar czf /tmp/dbis_core_$$.tar.gz -C "$PROJECT_ROOT" dbis_core`
+- Push single tar file: `pct push "$vmid" "$temp_tar" /tmp/dbis_core.tar.gz`
+- Extract inside container: `pct exec "$vmid" -- bash -c "cd /opt && tar xzf /tmp/dbis_core.tar.gz && mv dbis_core dbis-core"`
+
+### 4. ✅ Fixed Nginx Configuration
+**Issue**: Invalid `proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for` directive
+**Fix**: Changed to `proxy_set_header X-Forwarded-For $remote_addr` in `deploy-frontend.sh`
+
+## Files Modified
+
+1. `/home/intlc/projects/proxmox/dbis_core/scripts/deployment/deploy-api.sh`
+2. `/home/intlc/projects/proxmox/dbis_core/scripts/deployment/deploy-frontend.sh`
+
+## Next Steps
+
+The deployment scripts are now fixed and ready to deploy. The scripts will:
+1. Install curl first
+2. Remove conflicting Node.js packages
+3. Install Node.js 18 properly
+4. Copy files using tar archive method
+5. Configure services correctly
+
+**To redeploy:**
+
+```bash
+ssh root@192.168.11.10 "cd /root/proxmox/dbis_core/scripts/deployment && ./deploy-all.sh"
+```
+
+**Note**: If the dbis_core source code is not available on the Proxmox host, the scripts will automatically clone it from GitHub as a fallback.
