1. Understanding Debian's Philosophy

Debian is built around three core ideas:

• Stability – Software is tested thoroughly before release.

• Freedom – Debian is fully open-source (with optional non-free packages).

• Community – Thousands of volunteers maintain and improve the system.

Once you understand these principles, you'll appreciate why Debian releases less frequently but with exceptional reliability.

2. Meet APT: Your Package Manager

APT (Advanced Package Tool) is one of the best features of Debian. It makes installing, upgrading, and removing software incredibly simple.

A few essential commands:

sudo apt update  
sudo apt upgrade  
sudo apt install packagename  
sudo apt remove packagename  

APT connects to Debian's huge software repositories, giving you access to thousands of packages with no extra setup.

3. Enabling Non-Free and Firmware Packages

By default, Debian uses only free software. But many users need Wi-Fi drivers, media codecs, or GPU firmware.

To enable the additional repos:

sudo nano /etc/apt/sources.list  

Add or ensure the following sections exist:

main contrib non-free-firmware  

Save, exit, then run:

sudo apt update  

This gives you access to extra drivers and hardware support.

• neofetch – Shows system information

• vim or nano – Text editors

• firefox-esr or chromium – Web browsers

• gnome-tweak-tool (GNOME users) – Interface customization

• htop – Monitor system usage in real time

Install them easily:

sudo apt install neofetch htop

5. Keep Your System Updated

Debian rarely breaks, but staying updated helps keep your system secure:

Running this weekly is usually enough.
