aarch64 pip wheel not found for version 1.39.0

[vinnnyr]

What version of gRPC and what language are you using?

Attempting to install 1.39.0

What operating system (Linux, Windows,...) and version?

Ubuntu Docker Image, on an aarch64 machine

root@2b08dea4c476:/# cat /etc/os-release 
NAME="Ubuntu"
VERSION="20.04.3 LTS (Focal Fossa)

root@2b08dea4c476:/# uname -m
aarch64

What runtime / compiler are you using (e.g. python version or version of gcc)

root@2b08dea4c476:/# python3 --version
Python 3.8.10

root@2b08dea4c476:/# python3 -m pip --version
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)

What did you do?

In a fresh ubuntu docker container, running on an aarch64 machine, I attempted to pip install grpcio==1.39.0:

root@2b08dea4c476:/# python3 -m pip install grpcio==1.39.0

What did you expect to see?

Based on the conversation here: #21283 (comment)
The wheels for 1.39.0 are being built and hosted.

I expected to see the wheel being downloaded, like in version 1.38.0:

root@2b08dea4c476:/# python3 -m pip install grpcio==1.38.0
Collecting grpcio==1.38.0
  Downloading grpcio-1.38.0-cp38-cp38-manylinux2014_aarch64.whl (39.3 MB)
     |████████████████████████████▏   | 34.6 MB 4.3 MB/s eta 0:00:02^C
ERROR: Operation cancelled by user

What did you see instead?

You can see that this pulls down the tar for version 1.39.0, and builds the wheel, which is undesired.

Anything else we should know about your project / environment?

I don't think so.

I think the problem might be that your OS and pip versions are too old. The requirements for manylinux_2_24 are:

• pip >= 20.3 -- you have pip==20.0.2
• Ubuntu >= 21.04 -- you have 20.04.3
• CPython 3.8.10 -- you're good here.

I will close this as the aarch64 wheels definitely are there (but as noted, they are manylinux_2_24):
https://pypi.org/project/grpcio/1.39.0/#files

I think #27305 (comment) is right about why you are unable to install the wheels.
