Edit the **root crontab**:

```bash
sudo crontab -e
```

Add the following lines at the bottom:

```bash
# Daily at 03:00 – Run update only
0 3 * * * /path/to/auto-upgrade-proxmox.sh >> /var/log/auto-upgrade.log 2>&1

# Weekly on Sunday at 04:00 – Run update and reboot if successful
0 4 * * 0 /path/to/auto-upgrade-proxmox.sh && /sbin/reboot
