Detailed Description

[untergeek]

Duplicate issue of #1674.

This is a known issue with RHEL 7 and Centos 7 because of how old the provided version of Docker is.

See #1674 for more details, and a link to a workaround gist.

Feel free to update the Python versions in the workaround (both what is used in pyenv and in the Dockerfile) to 3.11.5, and update the OpenSSL version to whatever is most recent.

Oh, and the reason it doesn't work after 8.0.2 is because I had to update the Dockerfile and process to build both x86_64 and arm64 images and publish them in the same manifest. With the workaround, you will be making only an x86_64 image for your Centos box.
