I have this issue as well. I was running a custom 3.17 kernel with the Nouveau driver and then reverted back to 3.13. When I tried to switch back to the nvidia driver in 3.13 using the Software & Updates tool I got this error. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-331-updates in Ubuntu. https://bugs.launchpad.net/bugs/1351639 Title: package nvidia-opencl-icd-331-updates (not installed) failed to install/upgrade: trying to overwrite '/usr/lib/x86_64-linux-gnu /libnvidia-opencl.so.331.38', which is also in package nvidia-opencl- icd-331 331.38-0ubuntu7.1 Status in nvidia-graphics-drivers-331-updates package in Ubuntu: Confirmed Bug description: installing proprietary driver ProblemType: Package DistroRelease: Ubuntu 14.04 Package: nvidia-opencl-icd-331-updates (not installed) ProcVersionSignature: Ubuntu 3.13.0-32.57-generic 3.13.11.4 Uname: Linux 3.13.0-32-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 2.14.1-0ubuntu3.3 Architecture: amd64 Date: Fri Aug 1 23:49:06 2014 DuplicateSignature: package:nvidia-opencl-icd-331-updates:(not installed):trying to overwrite '/usr/lib/x86_64-linux-gnu/libnvidia-opencl.so.331.38', which is also in package nvidia-opencl-icd-331 331.38-0ubuntu7.1 ErrorMessage: trying to overwrite '/usr/lib/x86_64-linux-gnu/libnvidia-opencl.so.331.38', which is also in package nvidia-opencl-icd-331 331.38-0ubuntu7.1 InstallationDate: Installed on 2014-08-01 (0 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) SourcePackage: nvidia-graphics-drivers-331-updates Title: package nvidia-opencl-icd-331-updates (not installed) failed to install/upgrade: trying to overwrite '/usr/lib/x86_64-linux-gnu/libnvidia-opencl.so.331.38', which is also in package nvidia-opencl-icd-331 331.38-0ubuntu7.1 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-331-updates/+bug/1351639/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
