Ubuntu vs Debian

Ubuntu vs Debian for a VPS

Short answer

Both use the same package format and most of the same software. Ubuntu ships newer packages, five-year LTS support and vastly more tutorials; Debian ships a smaller base install, no Snap, no vendor telemetry and a more conservative release policy. For a low-RAM instance Debian idles in roughly half the memory. For a first server, Ubuntu's documentation advantage is decisive.

Which should you choose?

Ubuntu

Debian

Choose Debian for a minimal, predictable, long-lived server — especially on a 1 GB instance.

Frequently asked questions

Is Debian more stable than Ubuntu?

Debian stable changes less, which is what most people mean by stability. Ubuntu LTS is also production-grade; the real difference is release philosophy, not defect rate.

Can I use Ubuntu tutorials on Debian?

Almost always. The differences are mostly package names, sudo configuration and Ubuntu's use of Snap.
