Proposed fix: [actions/cache] 'Failed to save: Unable to reserve cache with key X, another job may be creating this cache.' — usually the key already exists (caches are immutable), so updated deps are
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: If you need to refresh the cache, use a key unique per run (e.g. include github.run_id) with restore-keys for the nearest match; otherwise ignore the warning when the key legitimately exists. Keep in mind the 10GB per-repo limit and 7-day eviction.
Option: Use per-run keys with restore-keys [evidence: official_recommended_action]
Applies when: Cache must be refreshed
Steps:
1. key: deps-${{ runner.os }}-${{ hashFiles('**/lockfile') }}-${{ github.run_id }}
2. restore-keys: deps-${{ runner.os }}-${{ hashFiles('**/lockfile') }}-
Expected: Each run saves a new entry; restores nearest
