Enable unattended updates on Ubuntu 24.04 server.

This isn't a demo — it's a deployment.  
Security updates happen weekly — automatically and quietly.

## Why this installer exists
Servers fail when patches are forgotten. Automated updates remove that risk.

## What this installer does  
✔ Applies weekly security fixes  
✔ Handles system package upgrades  
✔ Runs without user sessions  
✔ No interaction required  

## What this installer does *NOT* do
It won’t stop you from running the script without reading the documentation like there’s no tomorrow.  
Skip the README, and whatever happens next is your headache, not a bug report.

## 1. Prepare the system

```
sudo apt update -y
```

## 2. Download the installer

```
git clone https://git.x-files.dk/server/auto-update-ubuntu.git
```

```
cd auto-update-ubuntu
```

## 3. Run the installer
```
sudo ./auto-update-ubuntu
```

## Automatic Defaults

| Setting | Enabled |
|---|---|
| Security & package upgrades | ✔ |
| Weekly unattended execution | ✔ Sundays @ 04:00 |
| Interactive prompts | ❌ None — unattended mode |

---

## Cron Job Location (Important)

This script does **not** create a user cron via `crontab -e`.

Instead, it deploys a root‑level update scheduler here:

```
/etc/cron.d/updatesystem
```

Meaning:

✔ runs as **root**  
✔ independent of user accounts  
✔ persistent across reboots  
✔ zero interactive maintenance needed

Modify schedule:

```
sudo nano /etc/cron.d/updatesystem
```

## Optional Features (toggle inside script)

| Feature | Default | Enable by uncommenting |
|---|---|---|
| Auto-remove unused packages | ✘ | `Remove-Unused-Dependencies = true` |
| Auto-reboot if required | ✘ | `Automatic-Reboot = true` |
| Reboot even with logged-in users | ✘ | `Automatic-Reboot-WithUsers = true` |

Reference inside script:

```
# sed -i '/Remove-Unused-Dependencies/ s/^\/\/\s*//' "$config2"
# sed -i '/Automatic-Reboot/ s/^\/\/\s*//' "$config2"
# sed -i '/Automatic-Reboot-WithUsers/ s/^\/\/\s*//' "$config2"
```

---

## Verify Status

```
systemctl status unattended-upgrades
journalctl -u unattended-upgrades -f
```

---

## Logs

```
/var/log/unattended-upgrades/
/var/log/apt/history.log

```
grep "Packages that were upgraded" /var/log/unattended-upgrades/unattended-upgrades.log
