`automatic-updates` waited for `musl` builds

从 .github/workflows/automatic-updates.yml 开始，比较链接的两个 workflow run，重点关注 musl-build 可用性检查。验证安全发布版本和缺失构建的处理方式。完成标准是：无需等待 musl builds 即可创建 Debian security-update PRs，同时在只有部分 musl builds 存在时，仍会更新可用的 Alpine releases。

Follows on from https://github.com/nodejs/docker-node/issues/2539

Current behavior

automatic-updates.yml did not create a PR for the June 18, 2026 security release until all musl builds were available.

The PR https://github.com/nodejs/docker-node/pull/2540 was created June 18, 2026 06:56 UTC and only after
https://unofficial-builds.nodejs.org/download/release/v22.23.0/node-v22.23.0-linux-arm64-musl.tar.xz was completed at 18-Jun-2026 06:28 (UTC).

Expected behavior

For security releases, as described in README > Release Availability, it is expected that Debian releases may be published without Alpine releases if the musl builds are not available.

If any musl builds are missing, this should not prevent automatic-updates.yml creating a PR for Debian releases.

For the situation where some but not all musl builds are missing, then the Alpine releases for which the musl builds are available should be processed and a PR created. (This situation is currently not documented or described anywhere.)

26.3.0

There's no musl build for version 22.23.0 yet.

so although this is a security release, which is supposed to bypass the need for musl builds, no PR is being created.

Note

Note that the situation recovered on its own. This issue is just described here to present an opportunity for improving the workflow for future security releases.
