What happened?

The package

noarch/pip-26.1.1-pyhc872135_0.tar.bz2

uploaded 3 days ago to

https://anaconda.org/channels/anaconda/packages/pip/files

incorrectly has python>=3.9 as a dependency in its metadata, although it is built from a wheel that requires python>=3.10 and it does not work in python 3.9.

I migrate this issue from pypa/pip#14024 by their suggestion.

Expected behavior or outcome

The package metadata should prevent conda from choosing this package as suitable for Python 3.9 ,i.e. a python>=3.10 dependency should be used.

This is a temporary fix:

conda install "pip<21.0.2"

Thank you for the report!

A hotfix has been put in place and pip-26.1.1 should no longer be installable in environments with python 3.9.
