Cannot pip install from PyPI feed connected to another feed

[fbiryukov_8162]

I have two python feeds: DevPyPI and PrdPyPI.
DevPyPI has a connector to PrdPyPI.
I publish mypackage on PrdPyPI.
mypackage shows up in DevPyPI (web interface) but it cannot be installed from DevPyPI using pip.

PS> pip install mypackage==1 -i https://domain.com/pypi/DevPyPI/simple --user --no-cache-dir
Looking in indexes: https://domain.com/pypi/DevPyPI/simple
Collecting mypackage==1
ERROR: Could not install packages due to an EnvironmentError: HTTPSConnectionPool(host='domain.com', port=443): Max retries exceeded with url: /pypi/DevPyPI/download/mypackage/1/mypackage-1-py3-none-any.whl (Caused by ResponseError('too many 500 error responses',))

Hello;

A 500 error should be logged in ADmin > Diagnostic Center, so if you can check there and find it, that should help us identify what could be causing it.

Is it only that package, or all packages? If it seems to be package-specific, please share the package to us (or a version that still breaks, but has sensitive information removed), then we can try to reproduce the bug and fix it.

Strange, I didn't receive a notification that you replied... Ah, I had to subscribe.

I just have reproduced the issue. Here's what I have in the Diagnostic Center.

First there is a warning (5 times the same).

My package is very simple, it has no dependencies and one python module. You could try this.

setup.py

from setuptools import setup

setup(
    name='mypackage',
    version='1',
    description='My package',
    author='My Name',
    author_email='My@Email.com',
    py_modules=["mypackage"],
    zip_safe=False
)

mypackage.py

print("Hello, world!")

The first error is a known issue, it's related to browsing for packages in the UI, and it's something we've already addressed. I'm not sure about the second error.

As for the package, can you provide a package file that we can actually upload to a test instance of ProGet?

Basically I want to take a package file, then upload it from the UI, then try to download it from the UI. By not involving Python tools, we can eliminate a lot of problems and simplify finding solution.

@atripp
I can't upload files here (except images). Can you get them from wetransfer?
If not, see packaging and uploading python packages.

[atripp]

Hello; we transfer would be great. I can download it, and attach to the internal ticket for this forum post! I don't have a local python environment, so best to just get files and manually upload.

[fbiryukov_8162]

@atripp The link will expire in 3 days: wetransfer

[atripp]

Thanks, just confirming it was received, and I've attached it to the internal ticket. Stay tuned!

Hello; thanks to your package, we were able to reproduce this, and it's going to fixed as PG-1695 in the next maintenance release. Thanks!
