In this article, we'll cover and compare some of the most popular Linux distributions. Furthermore, you'll be given the information you need to make a decision about which one to use, as well as the links to the official Linux downloads pages for each Linux distribution.
When people say "Linux," what are they actually referring to? Linux isn't technically an operating system itself, but a kernel that serves as the foundation for a fully packaged operating system.
Linux distributions, or distros, all share the same kernel but come preloaded with a slew of software and utilities. These additions are what make Linux usable out of the box and give the user an operating system experience. They're also what make each distribution unique. Such software usually includes a package manager, desktop environment, and other common tools you'd expect to find.
The Linux kernel is free and open source. Generally, most or all of the software included in a Linux distribution is the same way. GNU makes its way onto most distributions, which is a collection of free software. Some refer to this combination as GNU/Linux or LiGNUx, but it has become more common (and erroneous) to simply say Linux, with the understanding that GNU software is pretty much implied.
Choosing the right Linux distribution to download can seem a little overwhelming, as there are many options. In this guide, we'll try to make the decision process a little easier by comparing the most popular Linux distributions and helping you download the one that suits you best.
Ubuntu is probably the most well known among all the Linux distributions. It's developed by Canonical and based on Debian.
It's best known for being user friendly and having great support. Canonical publishes new LTS (long term support) releases every two years like clockwork, always breathing fresh life into the operating system and keeping it on par with the latest software developments.
Download Ubuntu by going to Ubuntu.com and clicking on Download. There's a desktop edition, server edition, and various flavors available if you prefer an alternative desktop environment.
CentOS is based on Red Hat Enterprise Linux. As a result, it's more tailored towards enterprise use, such as on a server.
CentOS is still marketed to desktop users as well, but this distribution has garnered its reputation as a server OS. It's incredibly stable and tested, making it a safe choice for a commercial environment. Unlike RHEL, it's totally free. You can download it from CentOS.org.
Debian is a titan among Linux distributions, spanning back to the early 90s and spawning multiple derivatives since then, most notably Ubuntu.
Debian has proven itself a solid choice for any computer. It comes with over 59,000 packages bundled and ready to be installed. Head over to Debian's website and click on Getting Debian to download it.
Fedora is sponsored mainly by Red Hat. The newest features and latest developments you find on this operating system are eventually pushed upstream to the Red Hat Enterprise Linux distribution.
Fedora is good for a variety of uses. It has multiple editions that you can download: Workstation (for a personal PC), Server (for servers), CoreOS (for cloud computing), and a couple of others. You'll find all the editions available for download on Fedora's homepage.
Linux Mint is another popular choice. It's based on Ubuntu (and therefore Debian) and prides itself on being very user friendly. If you are looking for a distribution that is very easy to use, this would be a wise choice.
There are a few different versions available, depending on which desktop environment you prefer. By default, Mint pushes the Cinnamon desktop, which they developed. Head over to Linux Mint's download page and select the copy you want.
Arch Linux is more for the die-hard Linux user. This distribution doesn't hold your hand or guide you through things; it just expects that you know what you're doing. With this approach comes a few advantages. Mainly, it makes the distribution extremely simple and minimalistic.
Arch Linux is a lean and mean operating system. You can download Arch Linux from their official download page.
A moment ago, I was talking about the extreme simplicity of Arch Linux. Well, Manjaro is based on Arch Linux, and a lot of that simplicity and minimalism has transferred over. However, Manjaro takes huge strides in making up for Arch's perceived coldness.
In Manjaro, you'll find a user friendly, speedy, and responsive operating system. This is a good choice for anyone - desktop and server users alike. Manjaro's download page has the operating system packaged with either XFCE, KDE Plasma, GNOME, or just command line. Take your pick.
OpenSUSE is sort of like the free version of SUSE Linux Enterprise, which is a commercial version of Linux in the same league as Red Hat. Although its marketing includes desktop systems, this distro is probably more suited for servers and system administrators.
OpenSUSE is very stable and reliable and has a large community of supporters. You can download either the Leap version (latest stable release) or Tumbleweed (rolling release) from OpenSUSE's website.
Red Hat Enterprise Linux is a commercial operating system meant for use on high end servers, mainframes, etc. When you buy a copy of Red Hat, in large part you're buying professional support. When something goes wrong, you can pick up the phone and talk to a professional about how to remedy it.
For businesses that can't handle any downtime, you can see why this is a big selling point. Red Hat is free to try or use for development purposes, and you can download it on Red Hat's download page.
Kali Linux is not your typical operating system. It's specifically meant for penetration testing and ethical hacking, which means it comes packed to the gills with tools for brute forcing passwords, packet sniffing, and much more.
It's based on Ubuntu and is completely free. You can get your own copy of it over on Kali's download page.
Puppy's speciality is in leaving a very small footprint. It barely takes up any system resources. It's not uncommon to see sysadmins carrying their own copy of Puppy Linux on a USB drive, because you can boot directly to it in no time and use the operating system without having to install it. You can even remove the boot medium after Puppy has finished loading itself into RAM.
If you want to breathe new life into an old PC, or carry your own Linux on USB for troubleshooting, or if you just favor Puppy's small footprint philosophy, you can download it from the official site.
Clear Linux is developed and backed by Intel. As a result, it's optimized for Intel hardware. It's a minimal distribution that is specifically built for cloud use-cases. It's a stateless operating system, meaning that user data and the operating system are completely separate.
Check out Clear Linux's download page to grab a copy.
Solus Linux is designed for home computing. This is a bit of an anomaly among Linux distributions, which are usually touted as being perfectly capable of running servers, if not outright focusing on it. Solus developed the Budgie desktop environment, which has become popular outside of Solus as well.
It's available with a few different desktop managers over on Solus' download page.
Trisquel is based on Ubuntu and consists entirely of free software. It's geared towards home users, small businesses, and educational centers.
The download page contains options for Trisquel (main version), Trisquel Mini (lightweight version), and Trisquel Sugar TOAST (educational environment for children).
PureOS is based on Debian and consists entirely of free software. Its main focus is on privacy and it ships with multiple utilities to enhance the user's online privacy and security.
Grab the ISO file on the download page of PureOS.
