[Debian-astro-maintainers] Bug#1151762: galpy: FTBFS: ModuleNotFoundError: No module named 'numpy._core._multiarray_umath'

[Santiago Vila]

Package: src:galpy
Version: 1.10.2-1
Severity: serious
Tags: ftbfs forky sid

Dear maintainer:

During a rebuild of all packages in unstable, this package failed to build.

Below you will find the last part of the build log (probably the most
relevant part, but not necessarily). If required, the full build log
is available here:

https://people.debian.org/~sanvila/build-logs/202610/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you cannot reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:galpy, so that this is still
visible in the BTS web page for this package.

Thanks.

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
The following compiled module files exist, but seem incompatible
with with either python 'cpython-315' or the platform 'linux':

  * _multiarray_umath.cpython-314-x86_64-linux-gnu.so

We have compiled some common reasons and troubleshooting tips at:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python 3.15 from "/usr/bin/python3.15"
  * The NumPy version is: "2.4.6"

and make sure that they are the versions you expect.

Please carefully study the information and documentation linked above.
This is unlikely to be a NumPy issue but will be caused by a bad install
or environment on your machine.
