Attempting to install any of the dotnetcore2 versions via pip fails with the same issue.

Environments tried:
MacOS 10.12.6, pip version 20.0.1
python:3.7 Docker image, pip version 20.0.1

Running a pip search shows that the package exists:

$ pip search dotnetcore2
dotnetcore2 (2.1.11)  - .Net Core 2.1 runtime

[svick]

First of all, why are you trying to install .Net Core using pip? The page for that package says that it's not intended for general use. And it seems it's not updated regularly. Instead, I'd suggest following this tutorial (for macOS, that involves downloading a .pkg).

Now, I'm no expert on pip, but based on my attempts, the log you posted is not the full log. Can you post the full output of pip install dotnetcore2 -v? For me, it starts with "Collecting dotnetcore2" and then goes on to list the locations it searches for that package, which could be the problem here.

@svick Here's the full -v output, looks like it is being raised directly from the GET call to pypi so maybe a mirror is down. Feel free to close as it probably isn't specifically related to dotnetcore2

I was only doing a manual install of dotnetcore2 to narrow down why installs were failing. The error was initially found from installing azureml-sdk in this Circle build https://circleci.com/gh/PrefectHQ/prefect/54827 with the error:

Closing. Looks to be directly related with the version of pip pypa/pip#7626

Tested 19.3.1 and 20.0.2 and both worked 👍

@joshmeek I'm glad to hear that you figured out where the problem was.
