I have tested installing linux-modules-nvidia-460 on each of
groovy:linux, focal:linux, and bionic:linux, confirming that each
assembles (passing the sha256 checks) and inserts (failing to find
hardware).

@tseliot has tested this also on his Nvidia hardware with good results.

Bug description:
  To allow decoupling of nvidia-graphics-drivers-<version> streams and
  versions from the underlying kernel versions we wish to be able to
  sign new kernel modules into an existing kernel after the fact.  Under
  bug #1898716 we added support for an Ubuntu Modules signing key
  certificate.  Rebuild the LRM package to make use of this new
  signature.

  This involves splitting the LRM package into three.  linux-restricted-
  modules first builds the nvidia-graphics-drivers-* we require signed.
  linux-restricted-generate then consumes the .o's produced in that
  build and forms a signing custom binary upload for this.  linux-
  restricted-signatures then consumes the signing result from the LRG
  upload and expresses clean redistributible signatures which are
  consumed by LRM at installation time.  LRG must be embargoed as it
  (necessarily) generates fully formed .ko files for signing.

  Additional process is added to the kernel build life-cycle to handle
  the privacy requirements of the LRG/LRS interaction.
