- Missing packages or files mentioned:
  - The failure is due to apt repository Release files not being available, not due to missing package names. Specific issues:
    - 404 Not Found for Release files:
      - http://security.debian.org/debian-security buster/updates Release
      - http://deb.debian.org/debian buster Release
      - http://deb.debian.org/debian buster-updates Release
    - Errors:
      - E: The repository 'http://security.debian.org/debian-security buster/updates Release' does not have a Release file.
      - E: The repository 'http://deb.debian.org/debian buster Release' does not have a Release file.
      - E: The repository 'http://deb.debian.org/debian buster-updates Release' does not have a Release file.
- Version mismatch / other context:
  - Base image used: python:3.5-slim, which pulls a very old Debian (buster-era). The Debian repositories for buster are now end-of-life, causing the 404s and missing Release files.
  - This indicates a mismatch between the old base image (Python 3.5 on slim) and current Debian repo availability; solution typically involves updating the base image to a newer Python version (e.g., python:3.9-slim or newer) or switching apt sources to archived repos.

Exact error message and exit code

- Exit code: 1
- During: Preparing metadata (pyproject.toml) for numpy

- Partial log context:

  - 12.76   × Preparing metadata (pyproject.toml) did not run successfully.

  - 12.89   ╰─> numpy

Missing packages or files mentioned
- numpy==1.11.1 (from -r /app/requirements.txt (line 1))
- Note: The error stems from building this old numpy version against Python 3.9 in the base image.

Version mismatch / environment context
- Base image: python:3.9-slim (Python 3.9)
- Requested package: numpy==1.11.1 (very old; likely unbuildable on Python 3.9)
- Result: pip attempts to build numpy from source; metadata generation fails due to a NameError in numpy's distutils (CCompiler not defined), indicating a compatibility/build tooling issue rather than a simple install error.

  - ERROR: Ignored the following versions that require a different python version: 3.10 Requires-Python >=3.10; 3.10.1 Requires-Python >=3.10; 3.10.2 Requires-Python >=3.10
  - ERROR: Could not find a version that satisfies the requirement pelican-ipynb (from versions: none)

- Missing packages/files mentioned
  - pelican-ipynb distribution not found (No matching distribution found for pelican-ipynb)

- Version mismatch information
  - The error text indicates pelican-ipynb requires Python 3.10+ (Requires-Python >=3.10), but the base image is Python 3.9-slim, causing a version incompatibility.

- Additional context
  - The failure blocks the build due to the unavailable/unsupported pelican-ipynb package for the current Python version.
