Python version pinning mechanism in docker-stack-foundation does not match comment description

[ehfd]

What docker image(s) are you using?

docker-stacks-foundation

Host OS system

Ubuntu 22.04

Host architecture

x86_64

What Docker command are you running?

docker run -it -p 8888:8888 quay.io/jupyter/scipy-notebook

How to Reproduce the problem?

Try to extend the containers based on docker-stacks-foundation and install other packages (such as RAPIDS.ai) with specific requirements for Python revision versions for Conda. The installation fails.

Command output

Pins seem to be involved in the conflict. Currently pinned specs:
 - python==3.11.7 (labeled as 'pin-1')

Expected behavior

    # Pin major.minor version of python
    mamba list python | grep '^python ' | tr -s ' ' | cut -d ' ' -f 1,2 | sed 's/\.[^.]*$/.* /' >> "${CONDA_DIR}/conda-meta/pinned" && \

Adding sed 's/\.[^.]*$/.* /' is the correct solution to the explanation of # Pin major.minor version of python.

Thus:

cat "${CONDA_DIR}/conda-meta/pinned"
> python 3.11.*

Actual behavior

cat "${CONDA_DIR}/conda-meta/pinned"
> python 3.11.7

Anything else?

Thank you for the issue.
Could you please create a PR with the proposed change?
If you also know how to do in a more clear way than grep, tr, cut and sed, that would be nice.

And if you want to make sure it won’t break in a future, please add a test here:
