   Severity: minor   
      
     Hi,   
      
     On most of my systems, I've APT Pin files in order to get the linux kernel   
   and related packages (firmware, etc.) from backports.   
   Recently, I tried to upgrade an up-to-date boorworm (with backports for the   
   kernel+firmware) to trixie (with backports for the kernel+firmware).   
   It fails with the following message:   
   Preparing to unpack .../252-firmware-nvidia-graphics_20251021-1~   
   po13+1_all.deb ...   
   dpkg-maintscript-helper: error: file '/usr/lib/firmware/nvidia/ad103' not   
   owned by package 'firmware-nvidia-graphics'   
   dpkg-maintscript-helper: error: file '/usr/lib/firmware/nvidia/ad103/gsp' not   
   owned by package 'firmware-nvidia-graphics'   
   dpkg-maintscript-helper: error: directory '/usr/lib/firmware/nvidia/ad103'   
   contains files not owned by package firmware-nvidia-graphics, ca   
   nnot switch to symlink   
   dpkg: error processing archive /tmp/apt-dpkg-install-JfnTpC/252-   
   irmware-nvidia-graphics_20251021-1~bpo13+1_all.deb (--unpack):   
    new firmware-nvidia-graphics package pre-installation script subprocess   
   returned error exit status 1   
      
     At this time, firmware-nvidia-graphics 20250410-2~bpo12+1 was installed.   
      
     I know that bookwork-backports -> trixie-backports is not officially   
   supported, hence the minor severity. I think the problem comes from the mix of   
   "dir-to-symlink change of nvidia/ad10{3,4,6,7}" [09624635e929] and the   
   usrmerge operation.   
     I fixed this by temporary removing the package and re-installing it after.   
   I initially tried to manually install firmware packages from trixie (and not   
   trixie-backports) and then upgrading to trixie-backports but I messed up   
   in the apt command line and removed the package...   
      
     I'm not sure if you want to try to support this non-standard upgrade path.   
   If not, this bug report will just document this behavior and a possible   
   workaround. If I've time, I will check if upgrading to trixie before   
   trixie-backports also work.
