Can't self update to latest preview 1.2.0a2 (missing sha256sum)

The full URL giving the 404 is https://github.com/python-poetry/poetry/releases/download/1.2.0a2/poetry-1.2.0a2-linux.sha256sum

It seems like whomever did the release forgot to generate and upload these checksum files onto GitHub as part of the release files (also called "assets").

@sdispater @stephsamson do you know who made the release?

[sdispater]

If you installed Poetry with the get-poetry.py script you can't and won't be able to upgrade to any 1.2 releases.

The release process has changed and has been simplified that's why we recommend to use the install-poetry.py script.

See https://python-poetry.org/docs/#installation and https://python-poetry.org/docs/master/#installation for more information about this transition and how to use the new installation script.

[staticdev]

@sdispater this is not the case.. I installed using install-poetry.py script.

[sdispater]

@staticdev

~/.poetry/lib/ is not the path where Poetry is installed with the install-poetry.py script, only with the get-poetry.py script.

So it seems that your are still using a Poetry version installed with the get-poetry.py script somehow.

[staticdev]

@sdispater this is a bit strange, since I use the ansible-role I developed to install it, and you can check in the code it uses install-poetry.py: https://github.com/staticdev/ansible-role-python-developer/blob/main/tasks/main.yml#L59

Anyhow.. doesn't this error have something to do with the missing poetry-1.2.0a2-linux.sha256sum as mentioned by @fredrikaverpil?

I have the same problem after installing with the install-poetry.py script (i also tried with the get-poetry.py just for cakes, same error).

EDIT: I just removed poetry completely and installed again via the install-poetry.py script, and now it works. I am not sure what changed.

[fredrikaverpil]

@emilhe @staticdev I think this is what @sdispater meant. You probably have to uninstall poetry altogether, and then reinstall using the new install-poetry.py.

@sdispater can you confirm this is the case, and I could maybe add this nuance into the docs via a PR.

Then this line in the docs (README.md and docs/_index.md) could be updated to e.g. say "The previous get-poetry.py installer is now deprecated. If you are currently using it you should uninstall poetry and reinstall it using the new, supported, install-poetry.py installer.".

[Kreshu]

I confirm, removing old installation with get-poetry.py --uninstall and installing with new script solves the issue.

[staticdev]

You are right, I made a confusion. I installed poetry in two machines and the one I got this error was with get-poetry.py.
