It might be in our interest to base our builds based on conda-forge. Here is what comes to my mind to enable the migration: * [x] Cache conda-forge recent (and needed) packages from linux-64 and osx-64 and osx-arm64 builds * [x] Vincent: update [libblitz-feedstock](https://github.com/conda-forge/libblitz-feedstock/blob/master/recipe/meta.yaml) to match [ours](https://gitlab.idiap.ch/bob/conda/-/blob/master/conda/libblitz/meta.yaml) * [x] Tiago: remove vlfeat dependency from bob.ip.base ~~Fix and merge https://github.com/conda-forge/vlfeat-feedstock/pull/9~~ * [x] Laurent: Submit [zc.buildout](https://gitlab.idiap.ch/bob/conda/-/tree/master/conda/zc.buildout) to conda-forge * [x] Laurent: Submit [zc.recipe.egg](https://gitlab.idiap.ch/bob/conda/-/tree/master/conda/zc.recipe.egg) to conda-forge * [x] Amir: We need to use conda-forge docker image(s), their compilers, and mac requirements * [x] Remove `deps` from bob/bob.devtools> * [x] Start building bob/bob.devtools> based on conda-forge * [x] Update pin versions in bob.devtools * [x] Archive bob/conda> * [x] Amir: We need to delist packages in our channel that are already in conda-forge using metadata patches * [x] Delete all the beta packages * [x] Start building bob packages based on conda-forge * [x] Use https://github.com/conda-forge/miniforge/ instead of miniconda * [x] We might need to support `yum-requirements.txt` to support `pyopengl` which needs `mesa-libGL-devel` package installed.
