    What is the correct way to upgrade driver versions? Ubuntu 16.04 x64


      I'm new to team red because I'm tired of lying to a GPU about virtualization just to make team green drivers accept the OS they're installed on. I bought a RX 460 to get my feet with with team red again.


      I got my GPU passthrough setup working with Ubuntu 16.04 x64 desktop using the amdgpu-pro_16.30.3-315407.tar.xz install. This was fine but now I want to install the amdgpu-pro-16.40-348864.tar.xz driver and I don't understand the correct procedure.


      Eventually after the script choked and there was a absence of an uninstall script:

      Preparing to unpack .../vulkan-amdgpu-pro_16.40-348864_amd64.deb ...

      Unpacking vulkan-amdgpu-pro:amd64 (16.40-348864) ...

      dpkg: error processing archive /var/opt/amdgpu-pro-local/./vulkan-amdgpu-pro_16.40-348864_amd64.deb (


      trying to overwrite '/etc/vulkan/icd.d/amd_icd64.json', which is also in package amdgpu-pro-vulkan-d

      river:amd64 16.30.3-315407

      dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

      Processing triggers for libc-bin (2.23-0ubuntu3) ...

      Errors were encountered while processing:


      Log ended: 2016-11-06  12:30:38

      I was able to fix this with:

      dpkg -i --force-overwrite vulkan-amdgpu-pro_16.40-348864_amd64.deb


      dpkg -i --force-overwrite opencl-amdgpu-pro-icd_16.40-348864_amd64.deb

      and then apt-get install -f to force the package manager back into a semi-consistent state at which point the the install script uninstalled everything and installed everything fresh.


      My question is - this seems like kludge. What is the correct way to upgrade the drivers? Uninstall and then reinstall? Or is there a standard AMD upgrade path I'm unware of? Is there a better way I can do this in the future?
