Is this really a package / tool shipped with Kali?

I did some analysis on the bug, here are my results:

This issue is related to the package "python3-jaraco.context" which is used by the Python module "keyring". In version 6.0.0-1 the package is missing a module called "backports.tarfile" (https://github.com/jaraco/backports.tarfile/) which is used only with Python versions before 3.12.

See related bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1080355

Apparently the package version 6.0.0-1 was pulled from Debian testing where they are already using Python 3.12, and thus the bug does not occur. That's also the reason the Debian package maintainer refuses to fix the backports issue.

The bug will disappear when Kali shipps Python version 3.12, in the mean time it might be possible to package the backports.tarfile module.

https://www.kali.org/blog/kali-linux-2024-3-release/ says that Python 3.12 will be the default in Kali 2024.4 so this probably will solve itself by then.

Python 3.12 just landed in kali-rolling. If you update your system (apt update && apt full-upgrade), then maybe it's fixed?
