staged-recipes linux builds are failing

[isuruf]

Bug:

Since the release of new conda version a couple of hours ago, linux builds are failing with

+ setup_conda_rc /home/conda/staged-recipes /home/conda/staged-recipes-copy/recipes /home/conda/staged-recipes-copy/.ci_support/linux64.yaml
Traceback (most recent call last):

See for example https://dev.azure.com/conda-forge/feedstock-builds/_build/results?buildId=793801&view=logs&j=6f142865-96c3-535c-b7ea-873d86b887bd&t=22b0682d-ab9e-55d7-9c79-49f3c3ba4823

This is because the docker image has boa installed and boa requires an older conda-build and that version is incompatible with the newer conda.

[jaimergp]

Will a repodata patch for conda-build suffice?

[isuruf]

Don't think so. We need to either remove boa from docker images or have a new boa compatible with conda-build>=3.25 and mamba>=1.5.0

[isuruf]

Nvm, yeah, adding a conda constraint on conda-build would fix it.
