Recommended install method fails with SSL: CERTIFICATE_VERIFY_FAILED

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Linux Mint 19 Tara

• Poetry version: not possible to install

• Link of a Gist with the contents of your pyproject.toml file: no pyproject.toml

On macOS I had to create a symlink from OS certificates to python:

ln -s /etc/ssl/* /Library/Frameworks/Python.framework/Versions/3.9/etc/openssl

I’m having the same issue when trying to run the poetry installer. I’m not sure what else it would or even could be.

I’ve exported REQUESTS_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt, pip install works, pipenv works, other python applications that rely on ca certs work except for this installer. Any chance this can be reopened and looked further?
