+# fix(ci): Correct and improve Ubuntu version sync workflow
+
+This PR addresses several issues in the `Ubuntu Version Sync` workflow to improve its reliability and clarity.
+
+The workflow was previously failing due to a bash syntax error and was incorrectly applying Dockerfile checks to project-specific files.
+
+Key changes:
+
+- **Corrected Bash Syntax:** Fixed the syntax for associative array iteration in the `run` step, resolving the `Unexpected symbol: ' @'` error.
+- **Scoped Dockerfile Checks:** The synchronization check for Dockerfiles is now strictly limited to the `infra/` directory. This prevents the workflow from failing on PRs that only modify Dockerfiles within `projects/`.
+- **Improved Workflow Name:** Renamed the workflow to `Ubuntu Version Sync Check` for better readability in PR status checks, instead of displaying the raw filename.
