Poetry unable to install/update dependencies with Python 3.10

[DudeNr33]

• Poetry version: 1.5.0
• Python version: 3.10.12
• OS version and name: Docker image python:3.10-slim
• pyproject.toml: None

• I am on the latest stable Poetry version, installed using a recommended method.
• I have searched the issues of this repo and believe that this is not a duplicate.
• I have consulted the FAQ and blog for any relevant entries or release notes.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

Issue

I am unable to install or update any dependencies when running Poetry with Python 3.10 from the official Python Docker image.
The minimal reproduction example is described below.

With python:3.10-slim, Poetry is unable to even update itself after installing:

# apt -y update && apt -y install --no-install-recommends curl
[...]

# curl -sSL https://install.python-poetry.org | python3 - --version 1.5.0

# Welcome to Poetry!

This will download and install the latest version of Poetry,
a dependency and package manager for Python.

It will add the `poetry` command to Poetry's bin directory, located at:

/root/.local/bin

You can uninstall at any time by executing this script with the --uninstall option,
and these changes will be reverted.

Installing Poetry (1.5.0): Done

Poetry (1.5.0) is installed now. Great!

To get started you need Poetry's bin directory (/root/.local/bin) in your `PATH`
environment variable.

Add `export PATH="/root/.local/bin:$PATH"` to your shell configuration file.

Alternatively, you can call Poetry explicitly with `/root/.local/bin/poetry`.

You can test that everything is set up by executing:

`poetry --version`

# export PATH="/root/.local/bin:$PATH"
# poetry --version
Poetry (version 1.5.0)

# poetry self update 1.5.1

# poetry --version

# python --version
Python 3.10.12

Installing anything from a pyproject.toml leads to a similar result: Poetry prints out the required installs/updates, but then does nothing.

With python:3.11-slim, all works as expected:

# apt -y update && apt -y install --no-install-recommends curl
[...]

# curl -sSL https://install.python-poetry.org | python3 - --version 1.5.0
