- Exact error message and exit code
  - curl: (22) The requested URL returned error: 404
  - Exit code: 22

- Failing command/step
  - Step: [3/6] RUN mkdir -p /usr/local/swift     && curl -fsSL ${SWIFT_URL_BASE}/${SWIFT_TARGET_OS}/${SWIFT_PACKAGE}/ubuntu22.04/${SWIFT_PACKAGE}.tar.gz -o /tmp/swift.tar.gz     && tar -xzf /tmp/swift.tar.gz -C /usr/local/swift --strip-components=1     && rm /tmp/swift.tar.gz
  - Command sequence: create dir, curl the Swift tarball, extract, clean up

- Missing packages or files mentioned
  - No apt or filesystem packages are reported as missing. The failure is due to the Swift tarball URL returning HTTP 404 (not found), not due to a missing package in apt.

- Version mismatch info
  - The URL targets the Swift 5.9 release for Ubuntu 22.04 (swift-5.9-release). The 404 indicates the Swift 5.9 tarball is not available at the expected URL for ubuntu22.04, suggesting a mismatch or unavailability of that specific version/path.

Image swift:5.9-ubuntu22.04 NOT found on Docker Hub.
