dh-python in Noble, on architectures other than amd64, renames libdnf
binary modules and breaks them:
I: dh_python3 fs:418: renaming _module.so to
_.cpython-312-aarch64-linux-gnu.so
https://launchpadlibrarian.net/722671993/buildlog_ubuntu-noble-
arm64.libdnf_0.69.0-2.3build3_BUILDING.txt.gz
https://packages.ubuntu.com/noble/arm64/python3-libdnf/filelist
/usr/lib/python3/dist-packages/libdnf/_.cpython-312-aarch64-linux-gnu.so
On amd64 it ships the module named as intended:
https://packages.ubuntu.com/noble/amd64/python3-libdnf/filelist
/usr/lib/python3/dist-packages/libdnf/_module.cpython-312-x86_64-linux-
gnu.so
-
This causes dnf to break on arm64:
Traceback (most recent call last):
- File "/usr/bin/dnf", line 61, in <module>
- from dnf.cli import main
- File "/usr/lib/python3/dist-packages/dnf/__init__.py", line 30, in <module>

ImportError: cannot import name '_module' from partially initialized module

- Github Actions enable arm64 using Ubuntu 24.04 images yesterday, so this
issue is starting to show up when building rpm-based images (fedora/centos) on
Ubuntu 24.04 arm64 on Github as part of CI systems.

The issue was already fixed in Debian, but didn't make it in Noble:

It would be great to update dh-python in Noble, and do a binary rebuild
of libdnf to fix this issue.
+
+ [Test Plan]
+
+ * On a non-amd64 host running Ubuntu 24.04, install and run dnf:
+
+ $ dpkg --print-architecture
+ $ apt install -y dnf
+ $ dnf
+
+ * Without the bug, the help output should be displayed. With the bug, an
+ ImportError will be thrown.
+
+ * For good measure, the package contents should be listed to confirm
+ naming is correct:
+
+ $ dpkg -L python3-libdnf
+
+ [Other information]
+
+ The root cause of this bug is in dh-python, and is fixed in oracular and
+ newer. While the *best* fix would be to fix dh-python directly, and
+ rebuild affected packages, it seems that libdnf is the only affected
+ package. Hence, to simplify the fix, the workaround approach is
+ preferred.
+
+ In order for a package to be affected, it would have had to be built in
+ noble after dh-python 6.20240401 was uploaded, *AND* ship a file named
+ _module.cpython-312-*.so. On an amd64 host running noble, I see only
+ libdnf meeting this criteria:
+
+ nr@six:~$ apt-file search /_module.cpython
+ python3-libdnf:
/usr/lib/python3/dist-packages/libdnf/_module.cpython-312-x86_64-linux-gnu.so
+
+ [Where problems could occur]
+
+ The patch is in d/rules, and copies the incorrectly named _.cpython-*.so
+ to _module.cpython-*.so instead. I.e., manually fixing the incorrect
+ renaming. An error in this logic would result in either (a) the build
+ failing, or (b) the bug not being fixed at all.
