Package: debhelper Version: 13.5.2 Severity: normal dh_python3 has a *.pyinstall mechanism for installing files as part of a python module.
dh_missing appears to be ignoring the *pyinstall files and reports the python files as "missing", which from debhelper 13 causes the build to fail. You can see an example in the getfem++ build, e.g. https://buildd.debian.org/status/fetch.php?pkg=getfem%2B%2B&arch=amd64&ver=5.3%2Bdfsg1-3%2Bb11&stamp=1637484931&raw=0 getfem++ has debian/python3-getfem++.pyinstall containing debian/tmp/usr/lib/python*/*-packages/getfem/*.py getfem interface/src/python/*.so getfem so dh_python3 is handling the python files installed by the upstream build system to debian/tmp. But dh_missing reports the false positive: dh_missing: warning: usr/lib/python3.9/site-packages/getfem/__init__.py exists in debian/tmp but is not installed to anywhere dh_missing: warning: usr/lib/python3.9/site-packages/getfem/getfem.py exists in debian/tmp but is not installed to anywhere The following debhelper tools have reported what they installed (with files per package) * dh_install: libgetfem++-dev (5), libgetfem5++ (2), libgmm++-dev (2), python3-getfem++ (0) * dh_installdocs: libgetfem++-dev (2), libgetfem5++ (0), libgmm++-dev (0), python3-getfem++ (0) If the missing files are installed by another tool, please file a bug against it. When filing the report, if the tool is not part of debhelper itself, please reference the "Logging helpers and dh_missing" section from the "PROGRAMMING" guide for debhelper (10.6.3+). (in the debhelper package: /usr/share/doc/debhelper/PROGRAMMING.gz) Be sure to test with dpkg-buildpackage -A/-B as the results may vary when only a subset is built If the omission is intentional or no other helper can take care of this consider adding the paths to debian/not-installed. -- System Information: Debian Release: bookworm/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.15.0-2-amd64 (SMP w/8 CPU threads) Kernel taint flags: TAINT_OOT_MODULE Locale: LANG=en_AU.UTF-8, LC_CTYPE=en_AU.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages debhelper depends on: ii autotools-dev 20180224.1+nmu1 ii dh-autoreconf 20 ii dh-strip-nondeterminism 1.12.1-1 ii dpkg 1.21.1 ii dpkg-dev 1.21.1 ii dwz 0.14-1 ii file 1:5.41-2 ii libdebhelper-perl 13.5.2 ii libdpkg-perl 1.21.1 ii man-db 2.9.4-2 ii perl 5.32.1-6 ii po-debconf 1.0.21+nmu1 debhelper recommends no packages.
