Conda hangs when installing new Python version

Some of the output of conda search python is:

When I do conda install python=3.9 --channel conda-forge I get:

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: / failed with repodata from current_repodata.json, will retry with next repodata source.

Solving environment: \

It just hangs there. What to do?

Here is Solutions:

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

A work around is to create and activate a new virtual environment for conda:

conda create --name workaround
conda activate workaround

In the above example I used the name workaround for the new environment, but you can use any name you wish.

Note: Use and implement solution 1 because this method fully tested our system.
Thank you 🙂
