I noticed that the installation guide says to use --extra-index but I had found in the past that that installed an incorrect combination of packages. I can try that, but I'm surprised this has started failing only just today. I'm wondering if someone maybe deleted meson-python from the pypi.anaconda.org/scientific-python-nightly-wheels location?

Edit: See comments below. My CI tried to install the nightly build but there was no wheel for my platform so it installed from source and failed because meson-python was not available. My workaround was to add --only-binary ":all:" to my pip install command. The nightly builds could maybe be restarted?

I'm rerunning the CI job I had that failed. It looks like (see the logs above) that the wheel was not available and the sdist tarball was used instead.

Oh...nightly wheel builds failed:

Thanks for raising the issue. I see that indeed some of the linux builds are failing somewhat randomly -> #62124

I also see that some of the windows wheels are failing, I suppose that's not that you ran into, but something to fix as well (-> #62126)

Yes, correct. My CI only does "unstable/nightly" installs on ubuntu.
