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/202604/ 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:python-meshio, so that this is still visible in the BTS web page for this package. Thanks. -------------------------------------------------------------------------------- [...] debian/rules clean dh clean --buildsystem=pybuild dh_auto_clean -O--buildsystem=pybuild debian/rules execute_after_dh_auto_clean make[1]: Entering directory '/<<PKGBUILDDIR>>' rm -rf src/meshio.egg-info rm -f msh2xdmf.1 make[1]: Leaving directory '/<<PKGBUILDDIR>>' dh_autoreconf_clean -O--buildsystem=pybuild dh_clean -O--buildsystem=pybuild debian/rules binary dh binary --buildsystem=pybuild dh_update_autotools_config -O--buildsystem=pybuild dh_autoreconf -O--buildsystem=pybuild dh_auto_configure -O--buildsystem=pybuild [... snipped ...] adding 'meshio-5.3.5.dist-info/WHEEL' adding 'meshio-5.3.5.dist-info/entry_points.txt' adding 'meshio-5.3.5.dist-info/top_level.txt' adding 'meshio-5.3.5.dist-info/RECORD' removing build/bdist.linux-x86_64/wheel Successfully built meshio-5.3.5-py3-none-any.whl I: pybuild plugin_pyproject:168: Unpacking wheel built for python3.13 with "installer" module debian/rules execute_after_dh_auto_build make[1]: Entering directory '/<<PKGBUILDDIR>>' pandoc -s -t man debian/msh2xdmf.md \ -o msh2xdmf.1 make[1]: Leaving directory '/<<PKGBUILDDIR>>' dh_auto_test -O--buildsystem=pybuild I: pybuild base:385: cd /<<PKGBUILDDIR>>/.pybuild/cpython3_3.14_meshio/build; python3.14 -m pytest tests ============================= test session starts ============================== platform linux -- Python 3.14.4, pytest-9.0.3, pluggy-1.6.0 rootdir: /<<PKGBUILDDIR>>/.pybuild/cpython3_3.14_meshio/build configfile: pyproject.toml plugins: typeguard-4.4.4 collected 763 items tests/test_abaqus.py ...............
