Truststore dependency with Python 3.9

Issue

Hi, I have been able to install all my packages with mamba on Python 3.9 without any error until yesterday.
I'm getting an error for truststore not being installable because Python version is <3.10. I'm aware the package is not supported but I don't really need to install it and can't understand why it used to work until yesterday (I build several times a week through Docker so always a clean environment).

A simple "mamba install -y python=3.9" would raise the error.

I've been trying to set ssl_verify to False in conda config prior to the various installations but this hasn't been doing the trick.

Is there anyway to avoid having the truststore dependency/not installing it? As I said again, I'm not using the package at all and I can't really upgrade to Python 3.10 right now.

Many thanks

You are trying to change the Python version of your base environment. This will be complicated. I would rather suggest that you create a new environment instead. Newer versions of conda will require newer Pythons and thus this is not an advisable approach.

Thanks for your tip. It does work on a new plain environment but I need to use the base environment...
how come it works with Conda though?

Many thanks for your help

[hmaarrfk]

but I need to use the base environment...

You can install an older version of our installer. You may pin to a pretty old version of our installer 4.13.0-0
https://github.com/conda-forge/miniforge/pull/333/files

But you can always build your own Miniforge installer

[hmaarrfk]

I'm closing because we cannot unfortunately support such a large matrix of python versions for this installer. A conda-environment can likely fill your needs. Using the base is often not a requirement, more of a "convenience". Even the "base" environment is a "conda environment".
