Ubuntu LTS.
The world's most deployed Linux server.
The most widely used Linux server distribution in the world — with the largest community, the most documentation, and first-class support from virtually every software vendor.
From Debian's foundation to the world's server OS.
Ubuntu was created by South African entrepreneur Mark Shuttleworth and first released in October 2004. Built on top of the Debian GNU/Linux distribution, Ubuntu's goal from the start was to make Linux more accessible — regular releases, consistent hardware support, and a focus on usability that Debian's slower release cycle couldn't always provide. The name comes from a Southern African philosophy meaning "I am what I am because of who we all are."
Canonical Ltd., the company Shuttleworth founded to develop Ubuntu, introduced the Long Term Support (LTS) release model — a version released every two years that receives five years of official security updates, with an optional extended maintenance window beyond that. This predictability made Ubuntu the dominant choice for production servers and cloud infrastructure.
Today Ubuntu is backed by Canonical and has become the default OS for the majority of cloud deployments, including AWS, Google Cloud, and Azure where it is the most-launched server image. It is also the required OS for RemarkablePanel, our hosted control panel.

What makes Ubuntu the right — and wrong — choice.
An honest assessment to help you decide if Ubuntu LTS is the right OS for your Cloud Cube.
- Largest community and documentation — more tutorials, Stack Overflow answers, and guides than any other server OS
- Required for RemarkablePanel — the only OS that runs our hosted control panel
- Freshest packages in the apt ecosystem — newer software versions than RHEL-based distros
- First-class cloud support — default image on AWS, GCP, and Azure
- Excellent for modern stacks — Node.js, Python, Docker, and Kubernetes have best support on Ubuntu
- LTS predictability — 5-year support cycle with optional 10-year ESM for critical deployments
- apt is intuitive — package management is beginner-friendly compared to DNF/RPM
- cPanel not supported — cPanel/WHM only runs on AlmaLinux and CloudLinux
- Snap packages — some software uses Snap by default, which can have performance implications on servers
- Canonical influence — corporate decisions can affect package availability and defaults
- Not RHEL compatible — software built specifically for RHEL/CentOS may require adaptation
- Less conservative — more frequent package updates can occasionally introduce regressions
Ubuntu is the default choice for modern web stacks.
If you're running modern applications, RemarkablePanel, or need the widest possible software support, Ubuntu LTS is the natural choice.
RemarkablePanel
Ubuntu is the required OS for our hosted control panel — the only OS RemarkablePanel currently supports.
Modern web apps
Node.js, Python, Ruby, Go, and modern frameworks all have best-in-class apt packages and support on Ubuntu.
Docker & containers
First-class Docker and Kubernetes support — Ubuntu is the most common base for containerized workloads.
WordPress hosting
LAMP and LEMP stacks on Ubuntu are extremely well documented, with a massive ecosystem of guides.
DirectAdmin
DirectAdmin fully supports Ubuntu — a good combination if you want a familiar hosting panel without cPanel licensing costs.
Developers
Ubuntu's package freshness and cloud-native tooling make it the preferred choice for developer workstations and staging servers.
Ubuntu supports most panels — with one major exception.
cPanel is the only major panel that doesn't run on Ubuntu — everything else works well.
| Control Panel | Compatible | Notes |
|---|---|---|
| RemarkablePanel | Required OS — Ubuntu only | |
| cPanel & WHM | — | Not supported — cPanel requires AlmaLinux or CloudLinux |
| DirectAdmin | Fully supported | |
| Webuzo | Fully supported | |
| Enhance | Fully supported | |
| Plesk | Fully supported |
