Simple reproducer for virtual PackageRecord error

[maresb]

This is a lingering point of major breakage. Fails on both 1.4.0 and main.

Seems related to #202, #292, #381.

docker run --rm -it mambaorg/micromamba
micromamba install -y -c conda-forge mamba conda-lock git
mamba --version
# mamba 1.4.2
# conda 23.3.1
cat <<EOF > environment.yml
channels:
- conda-forge
dependencies:
- git
platforms:
- osx-64
EOF
conda-lock
pip install git+https://github.com/conda/conda-lock@4a667bd  # main, right after merging #290
conda-lock

Workaround: pin conda to 22.9

I think the issue with the glibc virtual package has been fixed in https://github.com/conda/conda/pull/12293. There is a very similar one with the osx virtual package though, I have opened https://github.com/conda/conda/pull/12715 that hopefully will fix this.

Wonderful, thanks so much!!!

Once this is released, it seems to me like we should be checking the Conda version in use by Mamba, and warn if it's older.

[maresb]

Conda v23.7.0 just became available. I am hoping that this is now completely solved. Please try and report back.

[maresb]

This should be solved by using the latest version of Conda. Ref: https://github.com/sagemath/sage/pull/35986#issuecomment-1656713210

Just seeing this now, very nice to see this fixed!

[maresb]

Agreed, thank you @lesteve for fixing it!!!
