Downloading and installing the pants launcher ...
Installed the pants launcher from <https://github.com/pantsbuild/scie-pants/releases/latest/download/scie-pants-linux-x86_64> to /home/runner/.local/bin/pants

Running `pants` in a Pants-enabled repo will use the version of Pants configured for that repo.
In a repo not yet Pants-enabled, it will prompt you to set up Pants for that repo.

This is the link, which looks the same as yours, other than the plus sign https://github.com/astral-sh/python-build-standalone/releases/download/20250612/cp[…]n-3.11.13+20250612-x86_64-unknown-linux-gnu-install_only.tar.gz

I think it's actually not on your end. Seems like GitHub Actions is a little flaky today

yeah, no worries sorry for the false alarm
