Error Cloning Python Environment Pro 3.4.3

[EricSimpson96]

I am attempting to clone my Python environment on a new PC running ArcGISPro 3.4.3, and I get the following error:

Destination folder removed.

I tried going to the URL that is indicated as having a 404 error, and it is indeed blank. Is there an alternative method I can try? It seems that Anaconda is changing their website. 

Thank you!

Is there some reason you can't clone from the Package Manager in Pro?

[EricSimpson96]

That is where I tried it when I received this error, sorry for forgetting to include that.

Hmm, the error messages look like they're coming from the command line.

At the urls above, the page gives a 'package not found'

At a shortened URL, the page looks like this:

so? This page might help. You might try creating your environment from the command line with venv and then installing the arcgis package. See also https://developers.arcgis.com/python/latest/guide/get-started/

Maybe check here as well. I'm not a conda expert, so take that for what it's worth. ESRI doesn't recommend it, but you could also use pip to install it.

Just ran into this same issue for the first time today -- commenting to follow.
