Ubuntu is built on Debian, so the two feel almost identical day to day: same apt package manager, same file layout, same commands. The differences are in release rhythm, support length and how new the software is. This guide helps you choose; for the wider comparison including AlmaLinux, Rocky and CloudLinux see choose a Linux distro for your VPS.
Before you start
- Know what you will run: a control panel, a web stack, Docker, or a specific app with its own requirements.
Side-by-side comparison
| Ubuntu LTS | Debian stable | |
|---|---|---|
| Backed by | Canonical (company) | Community project |
| Release cycle | New LTS every 2 years (April of even years) | Roughly every 2 years, when ready |
| Standard support | 5 years, extendable with Ubuntu Pro | About 3 years, plus about 2 years LTS |
| Package versions | Newer | Older, very well tested |
| Default footprint | Slightly larger (snap, cloud tools) | Minimal |
| Docs and tutorials | Largest volume online | Very good, and most Ubuntu guides apply |
| Panel support | cPanel, Plesk, CloudPanel, HestiaCP and others | Plesk, HestiaCP, aaPanel and others; not cPanel |
When to pick Ubuntu
- You want the newest stable versions of languages and tools.
- You plan to run cPanel on Ubuntu (see install cPanel on Ubuntu) or follow tutorials written for Ubuntu.
- You want the longest support window per release.
When to pick Debian
- You value stability and a lean base system above new features.
- You run long-lived services that rarely change, like DNS, mail or a VPN.
- You prefer no snap packages and no company-specific extras.
Tip: Unsure? Ubuntu LTS is the safe default for most VPS projects. Moving between the two later is mostly a matter of reinstalling and copying data, since commands are the same.
After installing
Both get the same hardening steps: follow first steps on a new Linux VPS, enable automatic security updates and set up a firewall with UFW on Ubuntu and Debian.
