Choosing Linux for a Small Office: Which Version and Why

Part 1 of 8 in the Linux Business Playbook.

The first thing people discover when they look into Linux is that there is no single "Linux" to download. There are hundreds of versions, with names like Ubuntu, Mint, Fedora and Debian, and the choice can feel like the first hurdle. It is not. For a small office the sensible shortlist is two or three names long.

What a "distribution" actually is

Linux itself is the engine: the core that talks to the hardware and keeps programs running. A distribution (often shortened to "distro") is a complete, ready-to-use package built around that engine: the desktop you see, the app store, the printer and Wi-Fi support, the update system. Think of it like cars. The engine might be the same, but one maker builds a sensible family sedan and another builds a track car with no cup holders.

For a business, you want the family sedan: polished, predictable and supported for years. That rules out most of the hundreds of options straight away.

The three sensible picks

Ubuntu LTS: the default choice. Ubuntu is the most widely used Linux on desktops and in business, which means the best hardware support, the most help online, and the most software packaged ready to install. The current long-term release is Ubuntu 26.04 LTS, released in April 2026, and it receives security updates until April 2031 at no cost. If you want a single answer, this is it.

Linux Mint: the familiar choice. Mint is built on top of Ubuntu's long-term base, so it inherits the same stability and software, but its desktop looks and behaves much like Windows: a taskbar along the bottom, a start-style menu in the corner, a system tray on the right. Staff who have used Windows for twenty years tend to find their feet in minutes. The current line, Linux Mint 22, is supported until April 2029.

Debian: the server choice. Debian is the rock-solid foundation Ubuntu itself is built on. It is conservative, changes slowly and is what we reach for on a box that sits in a cupboard doing one job: file sharing, backups, hosting an AI agent. It is less polished as a day-to-day desktop, so we do not usually put it on staff PCs.

A quick word on Zorin OS: another Ubuntu-based option designed to look as much like Windows as possible. It is a reasonable pick if the overriding goal is zero retraining, though it is a smaller project with a smaller community than Ubuntu or Mint.

What "LTS" means and why you want it

LTS stands for long-term support. Ubuntu releases a new version every six months, but only every second April release is marked LTS, and those are the ones that get security updates for five years instead of nine months.

For a business this is the whole game. An LTS release means your computers keep receiving security fixes until 2031 without you upgrading, reinstalling or retraining anyone. Compare that with the Windows 10 end-of-life scramble in 2025, when a great many perfectly good office PCs were declared unsupported. On Ubuntu LTS, the same PCs would still be covered. If you need longer still, Ubuntu Pro extends that to ten years, free for up to five machines.

What it runs on

This is the part that surprises most owners. Linux is light. A PC that struggles with Windows 11, or is not even allowed to run it, will typically feel faster on Ubuntu or Mint.

• Existing office PCs: anything from the last ten years with 8 GB of memory is comfortable.
• Refurbished business PCs: ex-corporate desktops and laptops from Dell, HP and Lenovo are plentiful, well built, cheap and well supported.
• Mini PCs: a silent box the size of a paperback, under $400, is plenty for a front desk.
• Laptops: most mainstream models work out of the box. Fingerprint readers and the odd Wi-Fi card are the usual exceptions, which we check before buying.

The practical rule: do not buy new hardware to try Linux. Put it on what you already have, or on a refurbished machine, and see how it goes.

What to avoid

Some distributions are built for enthusiasts who enjoy tinkering. They use a model called rolling release, where updates arrive continuously and the system is always on the newest version of everything. That is great fun on a hobby machine and a terrible idea on a front-desk computer, because "newest" sometimes means "broke this morning". Arch, Manjaro and similar names fall in this group. For an office, stick to the LTS family, and avoid anything obscure: a small community means harder support.

Worked example: a six-person accounting practice

A suburban Brisbane accounting practice with six staff was facing the Windows 10 cutoff. Four of their desktops were eight years old and could not run Windows 11, and the quote for new Windows machines plus licences was over $9,000.

Instead, they bought six refurbished Dell business desktops for a little over $1,500 in total, each with 16 GB of memory and a solid-state drive. We installed Ubuntu 26.04 LTS on all six, gave each the same desktop layout, connected the office printer and scanner, and pinned the handful of applications the staff use every day: a web browser for Xero and the ATO portals, an office suite, email and a PDF tool.

Staff training took one morning. The most common question was "where is the start button", which takes ten seconds to answer. Two months on, the owner's only complaint was that the machines were so quick the staff could no longer blame the computer for slow afternoons. They will not need to think about operating systems again until 2031.

What still needs Windows

Honesty matters here. A few things in a small office still want a Windows machine, and the right move is to keep one, not to force it:

• Specific legacy applications: an old practice-management package, a bespoke stock system or anything that only comes as a Windows installer and has no web version.
• Some bank and point-of-sale hardware: certain EFTPOS terminals, cheque scanners and label printers ship with Windows-only drivers.
• Adobe Creative Cloud: Photoshop, Illustrator and InDesign have no Linux versions. There are capable free alternatives, but a designer who lives in Adobe should stay on Windows or a Mac.
• Microsoft Access databases and heavy Excel macros: covered in Part 2.

In most offices this means one Windows PC stays, usually at the desk that needs it, and everyone else moves.

Key takeaway

For a small office, the choice of Linux comes down to Ubuntu LTS if you want the mainstream default, or Linux Mint if you want the Windows-like feel, with Debian for any machine that lives in a cupboard. Pick a long-term support release, put it on the hardware you already own, keep one Windows PC for the stubborn cases, and you are set until the next decade.
