Issue

I installed conda, and then did:

$ conda install -n root -c conda-forge conda-smithy

which completed without error. However, when I try to run smithy, I keep hitting the following error:

$ conda smithy ci-skeleton pmix
Traceback (most recent call last):
  File "/opt/anaconda3/bin/conda-smithy", line 6, in <module>
    from conda_smithy.cli import main
  File "/opt/anaconda3/lib/python3.11/site-packages/conda_smithy/cli.py", line 13, in <module>

    from conda.auxlib.packaging import (  # noqa: F401
ModuleNotFoundError: No module named 'conda.auxlib.packaging'

Doesn't matter what smithy command I use - always the same error. I have been unable to find anywhere that I can install the missing package.

Probably something dumb I've done, but I could use a pointer!

We have a similar issue when using conda 24.7.1 which started this weekend in our CI pipeline.
It started without any change to the code, the pipeline worked on Thursday on a PR and now it stopped working on the same PR on top of the same main branch.
Any news on this?

Edit:
Updating the conda-build package from 3.28.4 to the latest version 24.7.1 solved the issue for us.
Still weird it started happening all of a sudden
