The sigstore action requires Python 3.9+ and looks for 'python' (not 'python3'). On CentOS 7 (vfx2021 and vfx2022), the system Python is 3.7.9 and Conan is 1.47.0, both too old. Additionally, the sigstore GitHub action creates a venv which fails with uv-installed Python because the symlinks don't work with ensurepip. Solution: 1. Add ~/.local/bin to PATH early (before all setup steps) 2. Install Python 3.11 using uv with --default flag to create python, python3, and python3.11 symlinks in ~/.local/bin 3. Install Conan manually for CentOS 7 using python3.11 -m pip install --user to place it in ~/.local/bin 4. Install and run sigstore-python CLI directly for CentOS 7 instead of using the GitHub action 5. Keep get-conan and sigstore actions for other platforms With ~/.local/bin first in PATH, all tools (uv, python 3.11, conan 2.x) are found before old system versions.
