Issue
I tried creating a new conda environment with just 3 packages:
igozali@hostname $ mamba create -p ./test_env -c conda-forge python=3.10 opencv nginx

Looking for: ['python=3.10', 'opencv', 'nginx']
Encountered problems while solving.
Problem: nothing provides libopencv 4.2.0 py36_5 needed by opencv-4.2.0-py36_5
Using python 3.9 resolves properly, however!

I did a little bit of digging, but not sure I have a solution yet. I think nginx being pinned to libgd 2.2.* may be part of the issue. That forces use of a year old build of libgd, which has some similar dependencies as opencv. Seems to me like this is more likely a dependency conflict across those packages than a specific issue with the opencv package, but let's keep this open until more is understood of the issue.
igozali commented
Hey, thanks for looking into this @hajapy! One thing I thought was weird was if I had used python 3.9 instead e.g. mamba create -p ./test_env -c conda-forge python=3.9 opencv nginx, the env creation would succeed. I'm not much of a conda expert myself, but please let me know if I need to report this on a different feedstock repo as well.
hmaarrfk commented
It seems that the pinning is there from 5 years ago, when this was the accepted way of managing pinnings
I'm making a PR unblocking that pin. It might be a few days before it gets merged by a maintainer. Ping me on the nginx feedstock in 5 days if you don't hear back from anybody else.
igozali commented
Thanks again for looking into this! 🙏
hmaarrfk commented
probably.
igozali commented
Resolved indeed, thank you!
igozali@hostname $ mamba create -p ./test_env -c conda-forge python=3.10 opencv nginx
