Package: nvidia-cuda-gdb Version: 9.1.85-4+b1 Severity: normal Even after being rebuilt for the libncurses6 transition[1], nvidia-cuda-gdb depends on libncurses5. Clearly there's not much you can do about that, other than prodding Nvidia to release a version of it linked against libncurses.so.6, if they haven't done so already.
The libncurses5 package will continue to be be shipped at least until the buster release, so there is no hurry to do anything for the time being. 1. https://buildd.debian.org/status/package.php?p=nvidia-cuda-toolkit
