Install UnisonOS

There is not yet a supported production installation. The first downloadable software preview targets Ubuntu 24.04 LTS on x86-64 UEFI hardware.

Start from the v0.6.0-preview.1 release page. Download the bundle, SHA256SUMS, its Ed25519 signature, and the preview public key from that one release. Do not mix assets from different versions.

Native candidate route

The candidate is owned by unison-platform and uses:

The older compose.native.yaml route and repository-oriented installer remain useful engineering inputs. Supported public installation follows a separate promotion gate.

Checks already implemented

Automated preflight evaluates Ubuntu version, architecture, CPU, RAM, free storage, virtualization, UEFI, Docker/Compose, clock state, and audio presence. Unsupported platform or resource conditions block the simulated candidate.

The transaction layer supports versioned staging, digest verification, atomic activation, idempotent reinstall, injected-interruption recovery, repair, safe software removal, and separately confirmed factory reset.

What the published preview proves

The publication workflow rebuilt ten project images from recorded source commits, pinned all 13 runtime images by digest, signed project images, emitted SBOM and provenance evidence, applied available OS security updates, and published vulnerability results. A separate job downloaded the public release, verified the complete asset set, installed it into a clean temporary prefix, and rejected incomplete and tampered copies.

What is not yet validated

Do not treat this as production installation guidance until the project promotes an immutable release candidate and records:

Historical evaluator channels

Older WSL2, Linux VM, and split ISO artifacts are not part of the current download. Their pages remain as historical engineering context only: WSL2, Linux VM, and bare metal.

Review the release lifecycle and compatibility status before evaluating.
