readthedocs.org: Build Fails to Create Conda Environment

Details

• Project URL: https://readthedocs.org/projects/tethys-platform/
• Build URL (if applicable): https://readthedocs.org/projects/tethys-platform/builds/5043136/
• Read the Docs username (if applicable): swainn

Expected Result

I expect the docs for the dev branch of my project to build.

Actual Result

I encounter a failure during the creation of the conda environment (see full output below).

Things I have tried:

(1) Found this suggestion on the Conda issues page, so I attempted wiping the environment several times. (2) Reverted the back to commit with last successful docs build, but still failed with same error. (3) Created this Conda environment my dev machine successfully (using miniconda).

Here is the error:
