Looks good! Here is what happened when I tried it:

The progress bars worked properly but now I am wondering about those warning messages. I thought it might be due to older dependency versions in my environment but when I created a fresh env I found that they remain. Any ideas?

Those warnings are from anaconda-client. Check your ~./continuum/anaconda-client/config.yml for ssl verify entries. Some of them may be null

That fixed it, thanks!

I set both ssl_verify and verify_ssl (how are these things different?) to true in config.yml and the warnings went away.

Do you have any idea what might have set these flags to false (my only hypothesis is Anaconda Navigator?) as I'm pretty sure I've never manually edited this file before...

Something may have changed somewhere recently with anaconda-client. Are you able to test that on a completely fresh Anaconorda/Miniconda install without any of the standard config dirs?

I guess I could create a new user on my laptop then install miniconda to see if this reappears...

I'll try to test that as well. For now I'm going to let those two failed test combinations slide
