Version 0.10.0-2 of kbibtex is marked for autoremoval from testing on Wed 12 Feb 2025. It depends (transitively) on qtnetworkauth-everywhere-src, affected by #1090290. You should try to prevent the removal by fixing these RC bugs.
This package will soon be part of the auto-icu transition. You might want to ensure that your package is ready for it.
You can probably find supplementary information in the
debian-release
archives or in the corresponding
release.debian.org
bug.
