Description Mathieu Dubois-Briand 2026-06-18 10:34:32 UTC 
We got this failure, only once so far. Richard does not remember having any related change in his branch.

ERROR: babeltrace2-2.1.2-r0 do_unpack: Bitbake Fetcher Error: FetchError("Fetch command ['git', '-c', 'gc.autoDetach=false', '-c', 'core.pager=cat', '-c', 'safe.bareRepository=all', '-c', 'clone.defaultRemoteName=origin', 'rev-list', '-n', '1', 'd0e946a71faf5f0c2d7f1fb5b92a369983e9cf10'] failed with exit code 127, output:\npython3: error while loading shared libraries: libpython3.14.so.1.0: cannot open shared object file: No such file or directory\n", None)

Some extra data. This build has the vardepsexclude patches in which means it rebuilds every time PACKAGE_CLASSES is changed.

That meant for this build, lots of sstate tasks were invalid and being replaced.

There were two tasks running at the time:

pokybuild@debian13-vk-2:~/yocto-worker/pkgman-non-rpm/build/build/tmp/work/cortexa57-poky-linux/babeltrace2/2.1.2/temp$ tail -n 4 log.task_order

NOTE: python3 exists in sysroot, but is stale (python3.5aa073fd57c8f749a841396c1b5da03cbea6c1bfd33cf281366a6f32e5e2a26d vs. python3.caef672044878ee492a67390c83f8818dc20aa04f7143a53476e37e55f6469c3), removing.
NOTE: python3-native exists in sysroot, but is stale (python3-native.6363ac386d19013c4360e4df54382c1c8785b21476db12fc033716ae0466cf69 vs. python3-native.e99ddcbf0526f810136cf7cacc1d31009b37e69b803767e3e12a8858cade5556), removing

There is no mention or trace of git-replacement-native having been involved.

I'd therefore guess git from the host was finding libpython from the native sysroot and got upset when it was removed. Why it would do that...
Comment 3 Richard Purdie 2026-06-18 14:03:03 UTC 
Although python on the host ($ python --version) is Python 3.13.5 so perhaps git used python from the sysroot while it was being removed?
Comment 4 Richard Purdie 2026-06-18 14:53:59 UTC 
Bug triage noted we have an intercept script for git written in python3 which is why we would have triggered a python failure here.
