Production builds for Linux-MiniBook3 and Windows-MiniBook3 — scale-ready till with credits and FEFO batches.
Latest stable · v1.0.2 · Release notes
Linux
Ubuntu 22.04+ or equivalent · 4 GB RAM · Wayland or X11 · fuse2 for AppImage on some distros.
Offline-first
Sales stay on this machine. Cloud is for licence, payments, and Enterprise — never the lunch rush. Solo lab runs exceed 1M SKUs and 20M transactions.
Linux
Four ways to put Linux-MiniBook3 on the counter — pick the path that matches how you manage machines.
Recommended
One-line install
curl | bash installer — recommended for Ubuntu 22.04+, Debian 12, and similar. Creates a dedicated install root.
Offline tarball
Extract and run ./install.sh. Best for air-gapped desks. Data lives in ~/.local/share/MiniBook3/.
Debian / Ubuntu (.deb)
sudo apt install ./minibook3_1.0.2_amd64.deb — package-managed install for Debian-family desktops.
Portable AppImage
chmod +x and run. Ideal for trials and USB demos. Still uses ~/.local/share/MiniBook3/ for the ledger.
Windows
Installer for most shops, or a one-line PowerShell bootstrap when you want speed without hunting assets.
Verify & trust
Every production binary ships with a checksum manifest. Confirm before you open the register.
SHA256 checksums
Verify every binary before you trust the till. Use sha256sum -c SHA256SUMS.txt --ignore-missing.
Answered questions
Edge cases that break installs — answered before they break yours.
Which Linux option should I pick?
Use the one-line install.sh on a normal online desktop. Prefer the tarball when the shop is air-gapped. Use the .deb on Debian/Ubuntu if you want package management. AppImage is for trials and USB demos.
Where is the Windows portable zip?
When a portable zip is published on the release, it will appear here. Until then, use the installer or install.ps1 — both create a dedicated install root that updates can safely replace.
How do I verify the download?
Grab SHA256SUMS.txt from this page, download the artifact beside it, then run sha256sum -c SHA256SUMS.txt --ignore-missing (Linux/macOS) or an equivalent Windows checksum tool.
Will updating wipe my shop data?
No — the ledger lives outside the app bundle (~/.local/share/MiniBook3/ or %LOCALAPPDATA%\MiniBook3\). Install into a dedicated MiniBook3 folder so path-safe updates can apply.
