package nvidia-opencl-icd-331-updates (not installed) failed to install/upgrade: trying to overwrite '/etc/OpenCL/vendors/nvidia.icd', which is also in package nvidia-opencl-icd-331 331.79-0ubuntu1

Status changed to 'Confirmed' because the bug affects multiple users.

I think all nvidia-opencl-icd-* packages should Provides, Conflicts and Replaces on a new virtual package (e.g. nvidia-opencl-icd) to prevent them from overwriting each other. Similarly, the nvidia-*-uvm packages as well.

nvidia-graphics-drivers-331 (331.89-0ubuntu4) utopic; urgency=medium

  [ Alberto Milone ]
  * debian/71-nvidia.rules:
    - Make the rule more generic.

  [ Graham Inggs ]
  * debian/templates/control.in:
    - Drop the recommends on nvidia-libopencl1-$flavour,
      as nvidia-opencl-icd-$flavour already has its own
      dependencies.
    - Recommend the uvm driver instead of suggesting it.
    - Create the 'nvidia-opencl-icd' and the 'nvidia-uvm'
      virtual packages so that the real packages stop
      trying to overwrite each other's files
      (LP: #1328762, LP: #1347926).
