Verify an Omarchy ISO

Get the ISO from omarchy.org only. Then check the file against the official checksum below and the signature against the project key. This site does not host the ISO.

A lookalike site was suspended in 2026 for offering a fake Omarchy download. If the checksum here does not match your file, delete it. See how to spot a fake Omarchy site.

Questions people ask

Where is the official Omarchy ISO checksum?
In the GitHub release notes for each version (github.com/omacom/omarchy/releases) and, for 4.0.1 and later, in a .sha256 file next to the ISO on iso.omarchy.org. This page lists both.
How do I verify the Omarchy ISO signature?
Download the .sig file from iso.omarchy.org next to the ISO, import the Omarchy signing key (fingerprint 40DFB630FF42BCFFB047046CF0134EE680CAC571), and run gpg --verify omarchy-<version>.iso.sig omarchy-<version>.iso.
Does omarchylinux.org host the Omarchy ISO?
No. Never download an ISO from this domain or any domain other than iso.omarchy.org. This page only lists the official checksums and links to the official release pages.

Checksums are read from the official .sha256 sidecar files and from the GitHub release bodies at build time (2026-10-07T11:19). Always cross-check against the release page; if this table and GitHub disagree, trust GitHub.
