Summary (under 1500 chars):

- Exact error message and exit code:
  - fatal: not a git repository (or any of the parent directories): .git (exit code 128)

- Failing command/step:
  - Dockerfile step [5/5]:
    RUN git submodule update --init --recursive &&     make -C imageoptim build &&     make -C gifsicle build &&     make -C guetzli build &&     make -C pngquant build &&     make -C zopfli-png build

- Missing packages or files mentioned:
  - Not a missing apt package issue. The error indicates the working directory is not a git repository (the .git directory is missing), so git submodule update cannot proceed.

- Version mismatch info:
  - No explicit version mismatch reported. Base image is debian:oldstable-slim; build is for arm64 (as seen from the package list). No version mismatch noted in the log.

Notes:
- The root cause is attempting to run git submodule update in a context that isn’t a git repo. Ensure the Docker build context includes a .git directory (i.e., clone the repo with submodules inside the build) or modify the Dockerfile to fetch/substitute submodules differently (or skip submodules if not required).

- Exact error message and exit code
  - /bin/sh: 1: codesign: not found
  - make: *** [Makefile:15: pngout] Error 127
  - Exit code: 127 (failing command under the final RUN step)

- Failing command/step
  - Dockerfile step [7/7]: RUN make -C imageoptim build &&     make -C gifsicle build &&     make -C guetzli build &&     make -C pngquant build &&     make -C zopfli-png build
  - The error occurs during the imageoptim build when it tries to sign the downloaded pngout binary:
    - curl -LO https://www.jonof.id.au/files/kenutils/pngout-20230322-mac.zip
    - unzip -p pngout-20230322-mac.zip pngout > pngout
    - codesign -s "Developer ID" ./pngout --force
    - /bin/sh: 1: codesign: not found

- Missing packages or files mentioned
  - The codesign tool is missing (codesign: not found). This is a macOS signing utility; it is not available in this Debian-based container by default.

- Version mismatch info
  - Base image: Debian oldstable-slim (ARM64). The build fetches a macOS-specific binary (pngout from a mac zip) and attempts to sign it with codesign, which is not available on Linux. This cross-OS/tool mismatch leads to the failure.
