Cannot update to latest pre-release due to missing sha256sum file

[ashnair1]

• 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).

• OS version and name: Ubuntu 18.04
• Poetry version: 1.1.12

Issue

Updating to the latest pre-release fails due to missing sha256sum file

poetry self update -vvv --preview

Hello @ashnair1,

you cannot update to the latest pre-release version if you've installed poetry with the deprecated get-poetry.py script. Please uninstall the current poetry version with the get-poetry.py Script and reinstall it with the install-poetry.py script.

Thanks! Worked on MacOS 12.3 also.

Hello @finswimmer and @igorMIA, I would like to upgrade Poetry to the preview version and I have followed the instructions mentioned here to ensure that I have the newest version of Poetry available that was installed through the new script.

However, I still end up with an error like the one that was originally mentioned in this issue. While I recognize that this issue is now closed, I'm wondering if I could trouble you to point me in the right direction for what step I can next take to resolve this problem? While I recognize you are all busy, I would appreciate any help that you can provide.

• Since I have been using Poetry with the previous installation script I type curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python3 - --uninstall to uninstall it
• When I type the command which poetry, it outputs poetry not found
• When I type the command which python it output /home/gkapfham/.asdf/shims/python
• Please note that I am managing my Python installations with asdf which, as I recall, uses pyenv internally
• When I type python --version I see the following output: Python 3.10.5
• I then run the command curl -sSL https://install.python-poetry.org | python3 - and I see this output

Retrieving Poetry metadata

# 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:

/home/gkapfham/.poetry/bin

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

Installing Poetry (1.1.14): Done

Poetry (1.1.14) is installed now. Great!

You can test that everything is set up by executing:

`poetry --version`

Now when I type poetry --version I see the following output: Poetry version 1.1.14.

However, when I type the command poetry self update --preview I see the following output:

Updating to 1.2.0b3

  RuntimeError

  Could not find poetry-1.2.0b3-linux.sha256sum file

      258│         except HTTPError as e:
      259│             if e.code == 404:
    → 260│                 raise RuntimeError("Could not find {} file".format(checksum))
      261│
      262│             raise
      263│
      264│         checksum = r.read().decode().strip()

which is similar to the error that @ashnair1 originally posted.

Is there something that I am overlooking and doing wrong? Can you please help me to use the preview version of Poetry and then use the following approach to switch Poetry between different versions of Python?

#4101

Again, thanks for any insights that you can provide!

Hi @gkapfham , I'm hitting the same issue. I managed to workaround it via downloading manually the .whl file:

wget https://github.com/python-poetry/poetry/releases/download/1.2.0b3/poetry-1.2.0b3-py3-none-any.whl

and the installing it with pip. I know it's far from official solution, but maybe will unblock you.

Hello @ashnair1,

you cannot update to the latest pre-release version if you've installed poetry with the deprecated get-poetry.py script. Please uninstall the current poetry version with the get-poetry.py Script and reinstall it with the install-poetry.py script.

This worked for me !
An additional step that was needed after running curl -sSL https://install.python-poetry.org | python3 - --uninstall was to manually remove the directory where poetry was installed. The directory can be found with the command which poetry and removed with rm -r <path/to/poetry>.

[jonathandean]

Since get-poetry.py is no longer in the master branch you will need to uninstall with this url now:

curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/d222411ae9d01a04ec8eda348a65aa83852c37d0/get-poetry.py | python3 - --uninstall

Then I was able to install again using the current method in the docs
