If required, the full build log is available here: https://people.debian.org/~sanvila/build-logs/202503/ About the archive rebuild: The build was made on virtual machines from AWS, using sbuild and a reduced chroot with only build-essential packages. If you could not reproduce the bug please contact me privately, as I am willing to provide ssh access to a virtual machine where the bug is fully reproducible. If this is really a bug in one of the build-depends, please use reassign and add an affects on src:nvidia-open-gpu-kernel-modules, so that this is still visible in the BTS web page for this package. Thanks.
