Debian 12 "Bookworm" and Ubuntu 24.04 LTS "Noble Numbat" are the two most popular Linux choices for a VPS. They are closely related - Ubuntu is built on Debian and both use the APT package manager and systemd - so the real question is not "which is better" but "which trade-off fits your server": Debian's conservative stability, or Ubuntu's newer packages and commercial support.
Debian 12 vs Ubuntu 24.04 LTS at a glance
| Feature | Debian 12 Bookworm | Ubuntu 24.04 LTS |
|---|---|---|
| Base | Independent | Based on Debian |
| Release model | Stable every about 2 years, no fixed date | Fixed: LTS every 2 years, in April |
| Standard support | About 5 years including Debian LTS | 5 years, up to 12 with Ubuntu Pro/ESM |
| Package manager | APT / dpkg | APT / dpkg |
| Init system | systemd | systemd |
| Package freshness | Conservative, older but proven | Newer, backed by Canonical |
| snap preinstalled | No | Yes (snapd) |
| Minimal footprint | Very small | Slightly larger |
| Commercial support | Community | Canonical (paid, optional) |
| Best for | Lean, stable, long-running servers | Newer software and vendor support |
Stability vs freshness
Debian is famous for its conservative approach: packages are frozen and heavily tested before a stable release, so versions are older but extremely reliable. This is ideal for a server you want to set up once and leave running for years with minimal surprises.
Ubuntu ships newer versions of the kernel and key packages and moves faster, which helps when your application needs a recent language runtime, database or library. Canonical curates and supports these packages, and much of the newest software is documented against Ubuntu first.
Support windows
An Ubuntu LTS release gets 5 years of standard security updates, extendable to 10 years (and beyond for some packages) with a free-for-personal-use Ubuntu Pro subscription. Debian 12 receives roughly 3 years of full support from the Debian team, followed by about 2 more years of Debian LTS - close to 5 years in total. For most VPS lifecycles either is more than enough.
Footprint and the snap question
A minimal Debian install is very lean, which is attractive on a small VPS where every hundred megabytes of RAM counts. Ubuntu Server is slightly heavier and ships snapd by default; snap packages are convenient but some administrators prefer the predictability of plain APT and remove or avoid snap on servers. Debian leaves that choice entirely to you.
Which one should you choose?
- Choose Debian 12 for a lean, rock-solid server, minimal moving parts and maximum predictability - web servers, mail, DNS, reverse proxies and long-lived infrastructure.
- Choose Ubuntu 24.04 LTS when you want newer packages, the longest support window via Ubuntu Pro, or software that targets Ubuntu first, such as many DevOps and machine-learning tools.
Both are available as one-click templates on every INET.WS KVM VPS, and because you get a full dedicated kernel you can switch between them or reinstall at any time.
