How to Set Up a Debian HomeLab on a Dell Optiplex Mini PC (2026)


I am looking for a way to install Debian on a new Dell mini PC (which does not support Windows 11) to replace an old laptop running Windows 7. I want the mini PC to perform automatic system updates (using `unattended-upgrades`) and automatically power on after a power outage or when the UPS battery runs out—features the old laptop lacked (as it didn't support auto-booting upon plugging in). While upgrading to a mini PC is a good idea, I wouldn't use a standard desktop tower for this purpose, as the machine will serve as a home server hosting local or private web applications.


Upgrading from Ubuntu to Debian allows for indefinite package updates without needing to reinstall the OS, thereby extending the security lifespan of your HomeLab server. For instance, while Ubuntu Server 26.04 reaches its End of Life (EOL) in April 2036, Debian offers a path for continued support beyond that timeframe.

Preparing to install Debian on a Dell mini PC:

Note: If your newly purchased Dell Mini PC comes with Windows 10 pre-installed, you will need to wipe the data and install Debian via USB.


1. Create your Debian image on a flash drive. Don't have Debian yet? Click here to download. Example if using rufus and ventoy.


2. To boot from a flash drive on the Dell Mini PC, press F2 to configure the USB boot settings.


3. When installing Debian, choose the option to erase data and install if Windows 10 is pre-installed.


4. After installing Debian, remove the USB drive.


5. To update and upgrade packages, run "apt upgrade" to keep the system up to date.


6. Install OpenSSH server.

Preparing to set up a HomeLab on Debian:


Tip: Make Ubuntu Server more like Debian by removing the desktop environment and unnecessary packages to free up disk space.


7. Install 1Panel (must run on port 80 only, and the secure entrance must be disabled) 
               Docker.


8. Assign a static IP address or set up a DHCP reservation for your HomeLab.


You're all set! You can customize the settings on your home server to your liking and proceed to install, run, and manage Docker containers or use the ssh command.

Updated May 20, 2026: Install DDoS Deflate on Ubuntu/Debian to protect devices and reduce internet resource consumption.

DDoS Deflate is a GitHub repository developed by @jgmdev (Jefferson González) - founded 5 years ago, repository age 7 years or longer. DDoS Deflate is now available on Ubuntu/Debian from GitHub @jgmdev, completely free of charge and without any subscription. Provides long-term DDoS protection anywhere! What is DDoS Deflate used for? It protects devices from high internet resource usage by attackers who often randomly guess IP addresses and manipulate website browsing speeds. To use DDoS Deflate as a firewall and avoid conflicts with iptables, using ufw might cause problems. Choosing FirewallD will not cause any issues. DDoS deflate protection is definitely possible with software installed on Ubuntu/Debian. Using a firewall in conjunction can provide even better protection on public, office, and home Wi-Fi networks. Alternatively, use a 4G LTE router, making sure the firewall is enabled. As mentioned regarding DDoS Deflate; for more information on its features, visit: https://github.com...

Block and permanently shut down the Pi-Hole V6 web server interface.

To permanently disable the Pi-Hole web interface, enter the following command. To keep DNS running without worry, I need to disable only local websites: sudo pihole-FTL --config webserver.port '' sudo systemctl restart pihole-FTL To restore the Pi-Hole web interface after it has been shut down, enter: sudo pihole-FTL --config webserver.port 80 sudo systemctl restart pihole-FTL There are two other methods: block ports 80 and 443 and add them to the firewall using the UFW command on Ubuntu to completely and permanently disable the Pi-Hole web interface. If the UFW order has an "allow" rule set, change the order to "deny" to block the local port. Use the UFW port to permanently disable the Pi-Hole web interface. http: sudo ufw deny 80 https: sudo ufw deny 443 In the UFW command, which blocks the Local Domain Name System (DNS) port 53, set the rule to "allow". DNS: sudo ufw allow 53 If you're using FTP (aaPanel) and DNS (Pi-Hole) at home, having a ...
