You can find additional information in my debian-devel announcement: https://lists.debian.org/debian-devel/2025/04/msg00310.html About the archive rebuild: The build was made on debusine.debian.net, using sbuild. You can find the build task here: https://debusine.debian.net/work-request/153970/ If this is really a bug in one of the build-depends, please use reassign and affects, so that this is still visible in the BTS web page for this package.
