[Bug 1247736] [NEW] [SRU] nvidia-opencl-icd-* should not conflicts/replaces on opencl-icd

[Launchpad Bug Tracker]

[Impact]
Users with proprietary Nvidia graphics drivers are unable to co-install CUDA and OpenCL applications.
The patches in comment #21 and #22 backport the fix from Utopic and resolve this issue by allowing nvidia-opencl-icd-* (Nvidia's OpenCL ICD) to be co-installed with ocl-icd-libopencl1 (the generic OpenCL ICD loader).

[Test Case]
sudo apt-get install nvidia-331 or sudo apt-get install nvidia-331-updates (does not require an Nvidia graphics card)
sudo apt-get install python-pycuda
sudo apt-get install python-pyopencl

This will result in the error message below.

The following packages have unmet dependencies:
 python-pyopencl : Depends: libopencl-1.1-1
                   Depends: libopencl-1.2-1
                   Depends: ocl-icd-libopencl1 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

A similar conflict exists between wine and nvidia-cuda-toolkit.

sudo apt-get install nvidia-331 or sudo apt-get install nvidia-331-updates (does not require an Nvidia graphics card)
sudo apt-get install wine
sudo apt-get install nvidia-cuda-toolkit

This will result in a warning similar to the one below.

The following extra packages will be installed:
  nvidia-libopencl1-331 nvidia-opencl-dev
The following packages will be REMOVED:
  ocl-icd-libopencl1 ocl-icd-libopencl1:i386 wine wine1.6 wine1.6-amd64
  wine1.6-i386:i386
The following NEW packages will be installed:
  nvidia-cuda-toolkit nvidia-libopencl1-331 nvidia-opencl-dev

[Regression Potential]
This fix only affects the relationships between packages and should not introduce any new bugs.  However, since packages that were previously difficult to install together will now be co-installable, new bugs in those packages may be exposed.

[Other Info]
It is possible to work around this issue by first installing the CUDA application, then installing ocl-icd-opencl-dev, and finally installing the OpenCL application. (See comment #7)
