I would advise you just use the regular conda forge channel. Nothing new has been added to the gcc7 channel for more than a year

Turbodbc hasn't been built for Python 3.8 on Windows. That's the main error you probably have.

Also for better error messages, you should update your conda installation. conda 4.3 is quite old.

Hi,

It is Python 3.6 - i have used - conda-forge also same error. Yes the conda is quite old, but it comes with ArcGIS Pro 2.50. I have deployed about about 200 packages in this environment, using conda and pip, without any issues.

For turbodbc i am now using a pypi wheel for installation.

@rudyvogt Can you run conda install with -vvv? Still, I think this probably will be solved by using a newer version conda. The version of conda shouldn't interfer with your ArcGIS installation.
