** Description changed: + [Impact] + + * The pep517 module vendored in pip is missing its toml dependency. + This is used to ... + * An explanation of the effects of the bug on users and + justification for backporting the fix to the stable release. + * This upload backports upstream's 20.1 patch, replacing pytoml with + toml, following pep517. + + [Test Case] + + # apt install python3 virtualenv + # virtualenv -p python3 foo + # foo/bin/python -m pep517.build + + Note: + ModuleNotFoundError: No module named 'toml' + + Ideally the virtualenv wouldn't even contain pep517, it would be + internal to pip. See LP: #1904945 + + [Where problems could occur] + + * Anybody who was expecting pytoml to be installed in Ubuntu Focal + virtualenvs will have their expectation broken. + They really shouldn't be expecting that, though. + + [Original Bug Report] + On a clean 20.04 machine (or container), observe the following: apt-get update apt-get install -y python3-virtualenv python3 -m virtualenv foo && source foo/bin/activate pip list You will notice there are a plethora of extra packages in the virtual environment that should not normally be there, resulting in a dirty virtual environment. The packages listed here are those that are bundled with pip: https://github.com/pypa/pip/tree/master/src/pip/_vendor To make matters worse, the latest release of pip bundles incompatible versions of libraries. The net result is that `pip install pep517` will show that it is already installed, and but `import pep517` will result in an ImportError. This problem has been fixed in the Debian Testing/Unstable python- virtualenv package. Could the Ubuntu package backport these fixes? This is blocking Ansible supporting 20.04 officially, since the dirty virtualenvs are causing our tests to fail. https://github.com/ansible/ansible/issues/69203
