I do not have this problem with Conda, just with Mamba

Describe your issue

I could not rebuild an environment that I had working previously (same machine, same .yml). Particularly, I'm getting this warning I haven't seen before: warning libmamba Problem type not implemented SOLVER_RULE_STRICT_REPO_PRIORITY

I originally posted this in conda/conda-libmamba-solver (https://github.com/conda/conda-libmamba-solver/issues/206) where the suggestion to add CONDA_CHANNEL_PRIORITY=flexible solved the issue.
