- Failing step/command:
  - [7/9] RUN spin build -- -Dallow-noblas=true -Dcpu-baseline=none -Dcpu-dispatch=none

- Exact error message and exit code:
  - RuntimeError: The `vendored-meson/meson` git submodule does not exist! Run `git submodule update --init` to fix this problem.
  - Exit code: 1

- Missing packages/files referenced:
  - vendored-meson/meson git submodule missing (causing the RuntimeError).
  - Also earlier: could not import file `.spin/cmds.py` to load custom command `.spin/cmds.py:build`.

- Version mismatch information:
  - None reported. The failure is due to a missing submodule, not a version incompatibility.

Key error details

- Failing command/step:
  - [7/9] RUN spin build -- -Dallow-noblas=true -Dcpu-baseline=none -Dcpu-dispatch=none

- Exact error message and exit code:
  - RuntimeError: The `vendored-meson/meson` git submodule does not exist! Run `git submodule update --init` to fix this problem.
  - Exit code: 1

- Missing packages or files mentioned:
  - Missing git submodule: vendored-meson/meson (submodule not present). Suggested fix: run git submodule update --init.

- Version mismatch / environment notes observed:
  - apt-get install step shows GCC-related upgrades during package install (the log mentions upgrading: gcc-12-base, libgcc-s1, libstdc++6).
  - Meson-related tooling was updated during build (meson-python and related components pulled in; initial Meson version seen was 0.61.2, later replaced by Meson 1.10.2 via upgrades).
  - These indicate version changes in the build environment, but the immediate failure is due to the missing vendored submodule, not a direct incompatibility.

Summary:

- Failing step (command): [6/8] RUN spin build -- -Dallow-noblas=true -Dcpu-baseline=none -Dcpu-dispatch=none
- Exact error message and exit code:
  - TypeError: 'ABCMeta' object is not subscriptable
  - exit code: 1
  - Evidence: Docker reported the failure at the spin build step with exit code 1
- Missing packages or files mentioned: None indicated (the apt-get install step completed; no missing-file errors shown)
- Version mismatch / compatibility info:
  - Base image: ubuntu:20.04 (Python 3.8 in /usr/local/lib/python3.8)
  - Spin version: 0.13 (installed via pip in the build)
  - Potential root cause: Spin 0.13 appears incompatible with Python 3.8 in this environment, causing a typing-related TypeError (Decorator = Callable[[Callable], Callable] using ABCMeta)
  - Spin code path implicated: /usr/local/lib/python3.8/dist-packages/spin/cmds/util.py, line where Decorator = Callable[[Callable], Callable] is defined
- Quick takeaway: This is likely a Spin/Python version compatibility issue (Spin 0.13 with Python 3.8). Consider using a Python version compatible with Spin (or upgrade Spin to a version that supports Python 3.8) or pin the environment to a known-good combination.
