You should either perform a full upgrade (instead of a simple apt install), or also "apt-get install" the nvidia-kernel-source-460-server package (and all the other installed packages, for that matter), since this is the package which includes the actual sources and the patches. In your case, you only updated the dkms package, and kept the old patches and sources.
