Installation then python downgrade causes certificate error on intel MacOS #341

Solution to issue cannot be found in the documentation.

Issue

When I use the MiniForge installer on Big Sur 11.6.5 , and then immediately install the python 3.9 package to downgrade I get an error message at the end of install during the "Retrieving notices" phase. Afterwards the installation does seem to have completed okay.

Installing other packages instead does not cause this issue.

I can recreate using these commands:

wget https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-MacOSX-x86_64.sh
chmod u+x Miniforge3-MacOSX-x86_64.sh
./Miniforge3-MacOSX-x86_64.sh -b -p ./env
conda install -c conda-forge -y python=3.9

The traceback is:

Why do you need to change the base environment. This isn't supported.

Please create a conda environment with the version of python you need.

joezuntz commented 2 years ago

That does not appear to be an option with the miniforge installer. Is the correct solution to download an older version of the miniforge installer?

joezuntz commented 2 years ago

I'll rephrase in case I'm using the wrong thing here. I am looking for a stand-alone installer script that creates an environment with python 3.9 in it. The latest miniforge installer script creates one with python 3.10 - it sounds like it's not possible to run that and then downgrade to python 3.9, and that the right thing to do is then start with an older installer script?

(Incidentally, the README for this repo says that the default installer installs 3.9, but it seems to be 3.10).

hmaarrfk commented 2 years ago

Yes. This is not a supported use case.

You can use the machinery here to build your own installers that fit your specific needs.

You can the specified version.

isuruf commented 2 years ago

@joezuntz, the solution is to create a new environment with conda create -n py39 python=3.9
