poetry fails to install packages (`poetry install` for an existing lock file)
or to
update it (`poetry update`):
Can't instantiate abstract class IsolatedEnv with abstract methods
executable, scripts_dir
at /usr/lib/python3/dist-packages/poetry/installation/chef.py:131 in _prepare

According to github bug: https://github.com/python-poetry/poetry/issues/8458 it
is caused by conflict (interactions?) with python3-build package.

Indeed, as https://github.com/python-poetry/poetry/issues/8803 explains, poetry 1.7.1 needs python3-build ^= 1.0.3 1, yet the Debian python3-poetry package just depends on python3-build without any version constraints and python3-build is still at 0.10.0-1 in Debian unstable.
Additionally, python3-poetry version 1.6.1+dfsg-2 also has an unbounded dependency on python3-build despite its /usr/lib/python3/dist-packages/poetry-1.6.1.dist-info/METADATA clearly specifying the dependency as "Requires-Dist: build (>=0.10.0,<0.11.0)".
Something is seriously wrong with dh_python it seems :-(

Emmanuel, do you have any plan to update python3-build and fix poetry's
dependencies?

sergiodj upload the new upstream release of python3-build [0]. -doc
package was added.
Meanwhile I will try to add some autopkgtest to detect this kind of
bugs.
Thanks!
