Since June 6, 2026, all deployments are failing during build with this error:
mise python@3.13.14 [1/3] install
mise ERROR Failed to install core:python@3.13.14: no precompiled python found for core:python@3.13.14 on x86_64-unknown-linux-gnu
mise ERROR Version: 2026.6.1 linux-x64 (2026-06-06)
I tried NIXPACKS_PYTHON_VERSION, PYTHON_VERSION, MISE_PYTHON_VERSION variables — none work.
The app was working fine before June 6.
Service: pickmania-ev (Python 3.13 / Flask / Gunicorn)

You can use version 3.13 instead to let mise pick the closest available version as a workaround.

You can use version `3.13` instead to let **mise** pick the closest available version as a workaround.

The MISE_PYTHON_VERSION variable is being ignored. The build still uses python@3.13.14 from railpack-plan.json. How do I override this?
