As of the release of GitLab 9.5 on August 22, 2017, GitLab provides signed Omnibus GitLab packages for RPM and DEB based distributions. This means that all packages provided on packages.gitlab.com are signed, starting with
9.5.0, and all future versions of supported branches (e.g.
9.4.x after August 22, 2017).
Omnibus GitLab packages produced by GitLab are created via the Omnibus tool, for which GitLab has added DEB signing via
debsigs in our own fork. This addition, combined with the existing functionality of RPM signing, allows GitLab to provide signed packages for all supported distributions using DEB or RPM.
These packages are produced by the GitLab CI process, as found in the omnibus-gitlab project, prior to their delivery to packages.gitlab.com to ensure provide assurance that the packages are not altered prior to delivery to our community.
Information on how to verify GitLab package signatures can be found in Package Signatures.
Information on how GitLab manages GPG keys for package signing can be found in the runbooks.
