Problem after adding astroconda channel

[shanosborne]

We had an issue submitted in the webbpsf repository by @PatrickOgle about an issue he had when trying add the astroconda channel as part of installing webbpsf.

WebbPSF uses the same installation instructions for astroconda as the astroconda docs, which is conda config --add channels http://ssb.stsci.edu/astroconda (found here https://astroconda.readthedocs.io/en/latest/installation.html). But Patrick says that after he added the astroconda channel this way, he was unable to create any new conda environments. You can see the full description of the problem here: spacetelescope/webbpsf#379

Since this seems more like a conda/astroconda issue, I wanted to reach out and see if you had seen this kind of behavior before with astroconda?
