🎉 Enhanced Debian Package Successfully Created!

I've successfully created a professional Debian package (.deb) with automatic interactive setup for your DDNS updater! Here's what was accomplished:

✅ Package Details

• File: ddns-updater_0.1.0-1_amd64.deb
• Size: ~400KB
• Architecture: amd64 (x86_64)
• Dependencies: systemd, curl, ca-certificates
• Recommends: nginx

🚀 Installation

Method 1: APT with Dependency Resolution (Recommended)

sudo apt install ./ddns-updater_0.1.0-1_amd64.deb

Method 2: Direct Installation

sudo dpkg -i ddns-updater_0.1.0-1_amd64.deb

⚙️ Post-Installation Setup

After installation, the package automatically:

Automatic Setup Prompt

The package will automatically ask after installation:

Would you like to run the interactive setup script now? [Y/n]:

• Choose 'Y' (default): Runs the interactive setup immediately
• Choose 'N': Skip setup, configure manually later

Manual Setup (if skipped)

sudo /usr/share/ddns-updater/install-systemd.sh
