This may lead to a less comprehensive review. WalkthroughThe Dockerfile was updated to use Python 3.11 instead of the default Python 3. This involved adding the deadsnakes PPA, installing prerequisites, updating package references to python3.11 variants across both GPU and non-GPU build targets, and setting python3 to point to Python 3.11 via update-alternatives.

Pull request overview
This PR updates the Python version in the Docker build configuration from the system default Python 3 to Python 3.11. The change aligns with MFC's minimum Python version requirement of 3.11 specified in toolchain/bootstrap/python.sh.
Key Changes
- Adds the deadsnakes PPA repository to access Python 3.11 packages on Ubuntu
- Replaces generic
python3packages with version-specificpython3.11packages - Configures Python 3.11 as the default

The package python3.11-distutils does not exist in the deadsnakes PPA. The distutils module was deprecated in Python 3.10 and removed in Python 3.12. For Python 3.11, you should either:
- Add
python3-pipback to install pip directly, or - Remove this package and rely on
ensurepip(already available in Python 3.11's standard library)
Since the bootstrap script at toolchain/bootstrap/python.sh already handles pip installation via ensurepip when pip is not available, the recommended approach is to remove python3.11-distutils and add python3-pip for explicit pip installation, or simply rely on the bootstrap script's ensurepip fallback.

The priority value in update-alternatives is set to 2, which is unusually low. Standard practice is to use higher priority values (e.g., 100 or higher) to ensure the intended version takes precedence. While this may work in a container environment where only Python 3.11 is installed, consider using a more conventional priority value like 100 to follow best practices and avoid potential conflicts.

This Dockerfile adds the third-party ppa:deadsnakes/ppa repository and installs packages from it during the build, creating a supply chain risk: if that PPA or its signing key is compromised, attackers could ship malicious Python binaries that run with root privileges in CI and access build secrets or modify artifacts. Prefer using only official distro/python images or vendor repositories, or at minimum pin packages to trusted sources and specific versions with integrity verification to limit this attack surface.

Replace python3-pip with python3.11-full to ensure pip compatibility with Python 3.11.
The generic python3-pip package is built for the base image's default Python version (3.10 on Ubuntu 22.04), not for Python 3.11. Using it as the default Python after update-alternatives can cause compatibility issues. Instead, use python3.11-full which includes the pip package manager for Python 3.11, or run python3.11 -m ensurepip after installation. This ensures pip is properly configured for the version being set as default.
🤖 Prompt for AI Agents
.github/Dockerfile lines 17-18: replace the apt package `python3-pip` with
`python3.11-full` (or alternatively install pip for 3.11 via `python3.11 -m
ensurepip`) because `python3-pip` targets the distro default Python (3.10) and
can cause pip/version mismatches after switching to Python 3.11; update the
package list to include `python3.11-full` so pip is installed and configured for
Python 3.11, or install/ensure pip for 3.11 immediately after installing Python
3.11.
