This page is the fastest way into the Linux content on TurboGeek that’s actually worth your time. Whether you spend your day on Ubuntu servers, RHEL fleets, Raspberry Pi builds or a desktop you keep breaking on purpose — start here and pick the lane that matches the problem in front of you.
TL;DR
- Coverage spans Debian-family (Ubuntu, Debian), RHEL-family (RHEL, Rocky, AlmaLinux), embedded (Raspberry Pi) and a handful of independent distros.
- Four content pillars: storage & disks, networking, package management, recovery & security.
- Articles are command-first — designed to be used while you work, not admired afterwards.
- If you’re new to Linux, jump to Beginners. If something is broken, jump to Daily ops. If you’re hardening a server, jump to Security.
What is Linux?
Linux is the open-source operating-system kernel that runs the majority of internet infrastructure — every major cloud provider, most web servers, the Android phone in your pocket, and the embedded boards inside cars, routers and home-lab gear. A “Linux distribution” (distro) is the kernel packaged with a userland (shell, package manager, init system, default tools) into something you can install and use day-to-day.
The distros covered on TurboGeek group cleanly into a small number of families. Debian-family systems use apt for package management and tend to dominate cloud images. RHEL-family systems use dnf and run the long-tail of enterprise environments. Knowing which family you’re on tells you 80% of what’s different between any two Linux machines you’ll touch. The canonical home of the kernel itself is kernel.org.
Start with the problem in front of you
New to Linux
Start with Install Linux for Beginners and What is Linux? for the conceptual ground. Once you have a machine running, work through the Ubuntu Server First 30 Minutes Checklist — it covers the things every new server should have done before anything else lands on it.
Something is broken right now
Disk full? Check disk space in Linux, then free up disk space. Process stuck? How to kill a process in Linux. Searching log files? Master grep and regex.
Hardening a server for production
Run through the Linux SSH hardening checklist first, then look at post-quantum SSH on Ubuntu 26.04 if you’re future-proofing. CrackArmor and AppArmor fixes covers the kernel-level mandatory access controls Ubuntu admins should know about.
