Hi, I hope this is the right mailing list for that error… So, https://packages.debian.org/source/buster-backports/nvidia-graphics-drivers always gives error 500 (internal server error). The pages for that source package in any other repo work fine. The only difference I could think of is that nvidia-driver package versions in buster-backports are different on 64-bit systems (450.66) and 32-bit ones (440.100), as can be seen at the bottom of https://packages.debian.org/buster-backports/nvidia-driver . No idea if it’s relevant to the problem or not...
