- Exact error message and exit code:
  Traceback (most recent call last):
  ... (repeated stack) ...
  ModuleNotFoundError: No module named 'distutils'
  
  ERROR: process "/bin/sh -c ... " did not complete successfully: exit code: 1

- Missing packages or files mentioned:
  - Missing Python module: distutils (ModuleNotFoundError: No module named 'distutils')
  - Implicitly suggests python3-distutils or equivalent is not installed for Python 3.12

- Version mismatch / environment notes:
  - Base image uses Ubuntu Jammy (22.04). Python 3.12 is being installed via the deadsnakes PPA, with packages like libpython3.12-stdlib (3.12.13-1+jammy1) and python3.12-dev/venv.
  - Deadsnakes notes (as shown in logs) indicate Python 3.12 may not be provided for jammy by that PPA, yet APT installs 3.12 packages (3.12.13-1+jammy1). The log also shows a deadsnakes-provided Python 3.12 environment being set up despite those notes.

Exact error and exit code

Failing command/step

- The failure occurs during python3.12 -m pip install --upgrade pip (ModuleNotFoundError for distutils)

Missing packages or files mentioned
- Missing module: distutils (No module named 'distutils')
- Although python3-distutils was listed for installation, the Python 3.12 runtime from the deadsnakes PPA appears to lack the distutils package support, causing the failure

Version mismatch / context
- The log includes a note about the deadsnakes PPA: "Note: Python 3.10 (jammy), Python3.12 (noble) are not provided by deadsnakes as upstream ubuntu provides those packages."
- The build is using Ubuntu 22.04 (jammy) base with Python 3.12 from the deadsnakes PPA, which is not fully aligned with the distro’s official Python packaging and leads to missing distutils in the Python 3.12 environment

Dockerfile context
- The failing step is the third RUN in the build, which installs Python 3.12 and runs pip to upgrade and install multiple Python packages.

Summary:
- Failing step: The Dockerfile RUN that adds the Deadsnakes PPA and installs Python 3.12, then upgrades pip and installs packages:
  RUN set -eux; \
      add-apt-repository -y ppa:deadsnakes/ppa; \
      apt-get update -y; \
      apt-get install -y --no-install-recommends \
          python3.12 \
          python3.12-venv \
          python3.12-dev \
          python3-distutils \
          python3-pip; \
      update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.12 1; \
      python3.12 -m pip install --upgrade pip; \
      python3.12 -m pip install numpy cython pytest pytest-xdist pytest-timeout pybind11 mpmath gmpy2 pythran ninja meson pooch hypothesis spin 'click<8.3.0'
- Exact error message and exit code:
  ModuleNotFoundError: No module named 'distutils'
  (during python3.12 -m pip install --upgrade pip)
  Exit code: 1
- Missing packages/files mentioned:
  - Missing Python module: distutils (ModuleNotFoundError: No module named 'distutils')
  - Despite installing python3-distutils in the apt step, distutils could not be found at runtime.
- Version/mismatch notes:
  - Base image uses Ubuntu jammy (jammy-20260210.1).
  - The Dockerfile enables the Deadsnakes PPA to install Python 3.12. The PPA description in the log notes that Python 3.12 is not provided by Deadsnakes for jammy because upstream Ubuntu provides those packages, yet the build proceeds to install Python 3.12 from that PPA. This indicates a potential mismatch between the PPA notes and what’s being installed.

- Missing packages/files or related issues mentioned
  - gpg-agent: probably not installed
  - The failure occurs during attempting to add the deadsnakes PPA and import its GPG key, which fails with exit status 2.

- Version mismatch / context notes
  - PPA description notes: Python 3.10 (jammy), Python3.12 (noble) are not provided by deadsnakes as upstream ubuntu provides those packages. This explains potential mismatches when trying to install Python 3.12 on Ubuntu 22.04 (jammy) via this PPA. 
  - Repository context shown: Debian/Ubuntu jammy (22.04) base; attempting to use deadsnakes for Python 3.12 leads to GPG/key import failure in this environment.

- Missing packages/files mentioned
  - Distutils module missing (No module named 'distutils') during Python 3.12 pip upgrade
  - The RUN installs python3-distutils, but the process still fails due to missing distutils in the Python 3.12 environment
  - PPA version note indicating Python 3.12 compatibility issues on jammy (Ubuntu 22.04)

- Version mismatch / other context
  - The Deadsnakes PPA description notes: “Ubuntu 22.04 (jammy) Python3.7 - Python3.9, Python3.11 - Python3.13” and explicitly that Python 3.12 on jammy is not provided by Deadsnakes because upstream Ubuntu provides that package
  - This indicates a version-mismatch/unsupported combination: attempting to install Python 3.12 via Deadsnakes on jammy (22.04) when 3.12 is not supplied for that release, which may contribute to the distutils module issue.

Error summary

- Failing command/step:
  - RUN in Dockerfile: RUN python -m pip install --upgrade pip     && python -m pip install .

- Exact error message and exit code:
  - Meson/Subprocess error:
    "../meson.build:196:2: ERROR: Problem encountered: Missing the `array_api_compat` submodule! Run `git submodule update --init` to fix this."
  - Follow-up:
    "9.070 error: metadata-generation-failed"
  - Docker build exit code:
    "exit code: 1"

- Missing packages or files mentioned:
  - Missing git submodule: array_api_compat (Meson build expects this submodule to exist)
  - Suggested fix: Run git submodule update --init

- Version mismatch / environment details:
  - Meson version: 1.10.2
  - Base image: python:3.12-slim (FROM line)
  - Run-time dependency reported by Meson: Python 3.12
  - Observed Python version changes during apt install: python3.13 and related dev packages were installed in the build step, while Meson reports 3.12, indicating a Python version mismatch between the base image and installed build tools
  - Project version shown in log: SciPy 1.18.0.dev0

Note: The failure originates from a package metadata generation step (due to the missing submodule), not from a pip/Python version incompatibility alone.

  - Deadsnakes PPA note in the log: “Note: Python 3.10 (jammy), Python3.12 (noble) are not provided by deadsnakes as upstream ubuntu provides those packages.” This indicates a version mismatch: Python 3.12 is not provided for Jammy by that PPA, complicating installation of python3.12 via this repo.

Failing step
- [11/11] RUN spin build --with-scipy-openblas --release

Exit code
- 1

Exact error messages (preserved)
- !! Could not import file `.spin/cmds.py` to load custom command `.spin/cmds.py:build`.
- Traceback (most recent call last):
  - ... (omitted intermediate lines)
- AttributeError: module 'spin.cmds.util' has no attribute 'extend_command'

What happened
- The Spin-based SciPy build failed while loading the custom Spin command defined in .spin/cmds.py.
- The runtime could not import the custom command, and the error ultimately is an AttributeError: spin.cmds.util has no attribute extend_command.

Missing packages/files / version mismatch info
- Missing/invalid file reference: .spin/cmds.py (custom Spin command) could not be loaded.
- Root cause appears to be a Spin API mismatch: the Spin module in the environment does not provide extend_command in spin.cmds.util, which SciPy’s .spin/cmds.py expects.
- This indicates a version mismatch between the Spin tool installed in the image and the Spin API expected by SciPy’s Spin-based build script.

Notes
- Environment uses Python 3.12 (as shown elsewhere in the log), with Spin installed at /usr/local/bin/spin; the failure is due to Spin API incompatibility rather than a missing system package.

No results found.

  - Exact failure: 
    - ERROR: process "/bin/sh -c spin build --with-scipy-openblas --release" did not complete successfully: exit code: 1

- Missing/mentioned items:
  - Could not import file .spin/cmds.py to load custom command .spin/cmds.py:build
  - AttributeError: module 'spin.cmds.util' has no attribute 'extend_command'
  - Interpretation: The .spin/cmds.py script expects a Spin API feature (extend_command) that is not present in the loaded Spin module
- Version/Mismatch information:
  - Spin version/API mismatch: spin.cmds.util lacks extend_command; indicates incompatibility between the Spin version in the environment and the .spin/cmds.py driver code
- File/paths:
  - /workspace/scipy/.spin/cmds.py
  - /usr/local/bin/spin
  - /usr/local/lib/python3.12/site-packages/spin/__main__.py
- Suggested actions:
  - Align Spin version with what .spin/cmds.py expects (install a Spin version that provides extend_command)
  - Alternatively modify .spin/cmds.py to match the current Spin API
  - Verify environment has the correct Spin API/version and that the .spin/cmds.py path is valid
  - If submodules are used, ensure .git directory is present in the build context or adjust submodule handling accordingly

  - Step: [4/11] RUN update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.12 1     && python3.12 -m pip install --upgrade pip
  - Context: attempting to switch to Python 3.12 and upgrade pip

- Missing packages or files mentioned
  - Distutils module missing: No module named 'distutils'
  - This occurs inside pip when importing distutils via pip._internal.locations._distutils

- Version mismatch information
  - The build uses Python 3.12 from the Deadsnakes PPA on Ubuntu Jammy (22.04).
  - Deadsnakes notes indicate Python 3.12 for Jammy is not provided by upstream Ubuntu packages, yet the log shows attempting to install/use Python 3.12 from that PPA.
  - The distutils module is typically provided by a package like python3-distutils; the log shows python3-distutils installed for Python 3.10, but not available for the Python 3.12 environment, causing the ModuleNotFoundError during pip upgrade.

Notes:
- The error arises specifically during the 4th build step (the Python 3.12 pip upgrade), not from earlier apt installs.
- This is a packaging/version-mismatch issue: Python 3.12 on Jammy via Deadsnakes lacks distutils support needed by pip.
