Fatal error: The following packages have unmet dependencies:
wine-staging-amd64: Depends: libvkd3d1 (>= 1.2) but it is not going to be installed
wine-staging-i386: Depends: libvkd3d1 (>= 1.2) but it is not going to be installed
Running 'apt search libvkd3d1' finds version 1.1-5, and no later versions are in bullseye backports currently.
The packages had to be rebuilt, and it looks like not everything got synced over. You can either download both the wine and vkd3d packages from the OBS and install locally, or wait for the repository here to be updated.
