Private token as env variables not working

[hadim]

We are running a private conda-forge like infrastructure (with a private conda channel) and our builds stopped working since boa is the new default in conda-smithy (see https://github.com/conda-forge/conda-smithy/pull/1507).

Here is the channel_sources we are using in conda_build_config.yaml:

channel_sources:
  - t/$PRIVATE_TOKEN/private_channel,conda-forge,channel_xx,channel_yy,defaults

Here is the error in our Azure private conda-forge like CI:

Traceback (most recent call last):

    entry = lookup_dict[get_url_from_channel(c)]
KeyError: 'https://conda.anaconda.org/private_channel/linux-64'

Is that bug or something that is not supported?

For now, this fix is to set build_with_mambabuild: false in the conda-forge.yml file for every feedstock we have.

For those struggling with the same issue the workaround is to prefix the channel with the URL:

channel_sources:
  - https://conda.anaconda.org/t/$PRIVATE_TOKEN/private_channel,conda-forge,channel_xx,channel_yy,defaults

It's not a proper fix since it used to work before boa but at least it works now :-)

ping @wolfv FYI!

Let's keep this open, but I am glad that you found a workaround!
