Unauthorized keyring from Azure DevOps

[AndreuCodina]

When I use the keyring authentication and try to install packages from a private registry in Azure DevOps, I receive 401 Unauthorized.
I log in with my Microsoft account with az login.
The installation currently works with pip instead of uv.

requirements.txt

sqlmodel==0.0.14
my-private-package==1.0.0

Execution:

$ uv --version
uv 0.1.39

$ uv pip install --system keyring artifacts-keyring
...

$ az login
...

$ uv pip install --system --extra-index-url=https://pkgs.dev.azure.com/mycompany/_packaging/MyFeed/pypi/simple --keyring-provider subprocess --requirement requirements.txt --verbose

I've tried to generate a token and executing:

--extra-index-url=https:// mytokenname@ pkgs.dev.azure.com/mycompany/_packaging/MyFeed/pypi/simple

But I get the same result.

Hmm, strange. They return a 401 for a package that doesn't exist?

Are you able to try running from this branch? #3292

Are you able to try running from this branch? #3292

How can I test it from that branch? I install uv with pip install uv.
