Ubuntu and Debian are close cousins — Ubuntu is built on Debian — so you can't really pick “wrong”. But there are real differences worth knowing before you spin up a VPS.
The short version
Choose Ubuntu LTS if you want newer packages, the biggest pile of tutorials and broad commercial software support. Choose Debian if you want maximum stability, a leaner base and a slower, more conservative update pace. Both are excellent; both run anything you're likely to deploy.
Release cadence
Ubuntu ships a new release every six months, with LTS (Long-Term Support) versions every two years that get five years of updates — LTS is what you want on a server. Debian releases "stable" roughly every two years and supports it for several years; its stable branch deliberately favours tested over new.
Package freshness
Ubuntu tends to carry somewhat newer versions of software in a given year, and many vendors publish .deb packages and install docs targeting Ubuntu first. Debian stable intentionally freezes versions for predictability — rock-solid, occasionally older. (If you need newer on Debian, backports exist.)
Stability & footprint
Debian's minimal install is famously lean and unopinionated, which some admins prefer for servers. Ubuntu Server is also lean but adds a few conveniences (and things like snap). On a small VPS both are light; the difference is more philosophy than megabytes.
Ecosystem & docs
Ubuntu has the larger volume of beginner tutorials and Q&A, so if you're newer to Linux you'll find more copy-paste help that matches your system exactly. Debian's documentation is excellent too, and skills transfer between the two almost completely — apt, systemd and the file layout are the same.
Honest take: for most people a Ubuntu LTS VPS is the path of least resistance; for those who value conservative stability and a minimal base, Debian is a great pick. You can deploy either from a clean image on our panel and reinstall any time.
On overnight.host
We offer Ubuntu 24.04 / 22.04 / 20.04 LTS and Debian 12 as clean KVM images with full root — plus AlmaLinux and Rocky if you want a RHEL-family system. Pick your OS in the order picker; reinstall to a different one from the panel whenever you like.
FAQ
Is Ubuntu or Debian better for a server?
Both are excellent. Ubuntu LTS gives newer packages and the most tutorials; Debian stable gives a leaner, more conservative, very stable base. Pick by preference — skills transfer completely.
Is Ubuntu just Debian?
Ubuntu is built on Debian and shares apt, systemd and the file layout, but it adds a faster release cadence, newer packages, some conveniences (like snap) and commercial backing.
Which has fresher packages?
Ubuntu generally carries somewhat newer versions in a given year, and many vendors target it first. Debian stable freezes versions for predictability; backports add newer ones when needed.
Can I switch between them later?
Yes — on a VPS you can reinstall to a different OS from the panel any time. Back up your data first; a reinstall wipes the disk.
