Issue

I'm trying to install a package from a private repo but I'm seeing different bugs in the process. First I add the repo by

poetry source add prodigy "https://download.prodi.gy"

Then I add http-basic auth with

poetry config http-basic.prodigy <my-licence-key> ""

And finally I'm trying to add the package with

poetry add --source=prodigy prodigy -vvv

which yields

However the first time I tried I got another error: 403 Client Error: Forbidden for url: https://s3.eu-... so I figured that my licence key was wrong (I later realized that it is most likely related to #4497). So I tried to add it again with poetry config http-basic.prodigy <my-licence-key> "" which then gave this error

Unable to store the password for poetry-repository-prodigy in the key ring: Can't store password on keychain: (-25299, 'Unknown Error')

I checked in auth.toml and it looks fine.... If I add verbose logging on the poetry config command then I get

I know this issue is getting out of hand but I'm not sure if these errors are all linked to eachother?

There is also an ongoing thread here.

Start with poetry/mixology/incompatibility.py around Incompatibility.str and poetry/mixology/version_solver.py around _add_incompatibility, reproducing the failure with poetry add --source=prodigy prodigy -vvv. Also inspect poetry/utils/password_manager.py and the shown macOS keyring trace for the separate configuration error. Done means the reported commands no longer produce the AssertionError or the unhandled keyring failure, with regression coverage for the reproduced cases.
