poetry install fails when updating certifi when poetry config virtualenvs.create false --local is set

[eoshea-cmt]

• 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).

• Ubuntu 20.04 (in docker)
• Poetry version: 1.1.8
• Link of a Gist sorry, I don't have this

Issue

There seems to be an issue running poetry install when:

• poetry updates the certifi package
• config virtualenvs.create is set to false

My understanding (guess) is that, since poetry updates packages in parallel, if it is updating the certifi package while updating others, it can fail to find a cert. In the stack trace that I will post, it is clear that certifi is updating when the error happens. I believe this is some race condition because it happened to a coworker 2/3 times when he encountered the bug.
In the case where I am posting, it was happening consistently.

A workaround for this is to move away from using poetry config virtualenvs.create false, which I can do in one project, but not another.

Any help would be appreciated.

Hello @eoshea-cmt,

how did you install poetry? With pip? If so stop doing this. Always install poetry with the official installer or pipx. That's the only way to make sure, that poetry's own dependencies get not updated/deleted.
