Hi!

While preparing the Python 3.15 migration we realized that some Python
packages were shipping broken metadata directories, which leads to
errors when trying to import these directories with code running on
Python 3.15.

To avoid shipping any additional broken directories, dh-python
7.20261019 now throws an error at build-time.

Unfortunately, python-fasteners is one of the affected packages and
fails to build with the latest dh-python [1].

Most of these errors can be fixed by being more strict with the files
considered for installation. I'll try to submit a patch for this ASAP.

Happy hacking,

Hello,

Bug #1151467 in python-fasteners reported by you has been fixed in the
Git repository and is awaiting an upload. You can see the commit
message below and you can check the diff of the fix at:

https://salsa.debian.org/openstack-team/python/python-fasteners/-/commit/3e381cd594fd083f3dae060c1d9866a9aa79dd1e
When installing for several Python versions, dh_python3's new
dist-packages merge aborts on the wheel's top_level.txt metadata
(fs:172: no merge driver for that file), as seen in the Python 3.15
migration rebuilds. Build and install for the default python3 only,
which is correct for this pure-Python, arch:all package.
