FTBFS gitsome 0.8.0+ds-9 fails to build without python3-six

[Hans Joachim Desserud]

gitsome 0.8.0+ds-9 was synced from Debian to Ubuntu Oracular but fails to build with the following error message:

ModuleNotFoundError: No module named 'six'

(https://launchpadlibrarian.net/730825470/buildlog_ubuntu-oracular-amd64.gitsome_0.8.0+ds-9_BUILDING.txt.gz)

Interestingly enough, the same package builds successfully in Debian Sid. One notable difference is that python3-six is installed as part of the build:
Get: 102 http://deb.debian.org/debian unstable/main amd64 python3-six all 1.16.0-6 [16.3 kB]
(https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/gitsome.html)

I could not find a corresponding line in the build log for Ubuntu. I am not sure why, but adding the build dependency manually fixes the build.

The question is how to address this. I will add a debdiff below which resolves the issue to make gitsome build successfully. Normally the patch should be forwarded or applied to Debian, though for now this only seems to be a problem in Ubuntu. Also, it looks Debian is pulling in python3-six as a transitive dependency but I don't know how to drill down where it comes from to see the actual delta between Debian and Ubuntu causing this issue.

Hi Hans,

I recently fixed a similar issue for python-chemspipy package [1]. Sharing here in case it helps.

Yes, the needed fix is adding python3-six as you did. Why?

Summarizing, the key is python3-urllib3: we're syncing it from experimental, not from sid/trixie, and this latest version from experimental doesn't have the six module embedded as it was used to have (check changelog [2]).

python3-urllib3 comes from python3-request that comes from python3-pytest (as Build dependency in gitsome/d/control).
