@abn I have Uninstalled poetry like this curl -sSL https://install.python-poetry.org | python3 - --uninstall and installed it back like this curl -sSL https://install.python-poetry.org | python3 -

When I do poetry self update it still installs packaging 23.0 instead of 23.1 Like it says is the MR https://github.com/python-poetry/poetry/pull/9032/files

Am I doing something wrong?

[abn]

Does pipx install poetry perform any better?

[abn]

Am I doing something wrong?

I don't think so, this is likely because poetry when updating is locking the version to 23.0.

[rga-coding]

Does pipx install poetry perform any better?

I can't use pipx, the server is bein managed by someone else. I can't just install packages.

[abn]

You can install pipx into user site by python -m pip install --user pipx.

You can alternatively go the virtual environment poetry is installed in, typically in ~/.local/share/pypoetry/venv, and then ./bin/python -m pip install -U packaging.

The issue should go away with the next patch release.

[mickeykkim]

I'm still getting this error with poetry 1.8.1

[clintonroy]

@mickeykkim you'll need to give a lot more details for us to be able to try to reproduce your problem, how are you attempting to install poetry?

[mickeykkim]

After updating my poetry lockfile, my problem has been fixed. Apologies.
