rules_python is not working with uv 0.10+

[neckbosov]

🐞 bug report

Affected Rule

The issue is caused by the rule: `@rules_python//python/uv:uv.bzl` : `uv.configure`

Is this a regression?

No

Description

When trying to configure rules_python to use uv 0.10 or 0.11, I'm gettting error downloading uv for powerpc64 (my host system is x86_64 so I don't know why I would even need that).

🔬 Minimal Reproduction

Create a Bazel project with rules_python, configure uv, e.g., to 0.11.2, add lock rule to BUILD.bazel, try to build project

🔥 Exception or Error

Anything else relevant?

It seems that the file "uv-powerpc64-unknown-linux-gnu.tar.gz.sha256" is no longer uploaded by astral's pipeline and we fail because we attempt to index the binary download location for that file. The fix here is to remove the powerpc64 support until they fix it.

@neckbosov Why do you need PPC64 (Big Endian) builds? We dropped support (astral-sh/uv#17626) since they aren't supported by linux distros nor manylinux anymore.

@konstin exactly, I don't need it, but rules are downloading it.

I see, sorry I misunderstood the original bug report.
