This occurs in 18.04 because versions 340 and 390 are attempted to be installed at the same time and they apparently both want to modify /lib/udev/rules.d/71-nvidia.rules
apt-get install -f was not able to fix the situation. Workaround: remove all packages mentioning nvidia 340 and 390 (beware you may want to check what this does): # show the packages we're about to remove dpkg-query -W | egrep 'nvidia.*3[49]0' | perl -naE 'say $F[0]' # remove them dpkg-query -W | egrep 'nvidia.*3[49]0' | perl -naE 'say $F[0]' | sudo xargs dpkg -P Now install *ONLY* the version 340 one. And then both apt and subsequently the nvidia driver worked for me. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-340 in Ubuntu. https://bugs.launchpad.net/bugs/1767116 Title: package nvidia-340 (not installed) failed to install/upgrade: trying to overwrite '/lib/udev/rules.d/71-nvidia.rules', which is also in package nvidia-kernel-common-390 390.48-0ubuntu3 Status in nvidia-graphics-drivers-340 package in Ubuntu: Confirmed Bug description: i don't know ProblemType: Package DistroRelease: Ubuntu 18.04 Package: nvidia-340 (not installed) ProcVersionSignature: Ubuntu 4.15.0-19.20-generic 4.15.17 Uname: Linux 4.15.0-19-generic x86_64 NonfreeKernelModules: nvidia_drm nvidia_modeset nvidia ApportVersion: 2.20.9-0ubuntu7 Architecture: amd64 Date: Thu Apr 26 16:22:30 2018 DuplicateSignature: package:nvidia-340:(not installed) Unpacking nvidia-340 (340.106-0ubuntu3) ... dpkg: error processing archive /var/cache/apt/archives/nvidia-340_340.106-0ubuntu3_amd64.deb (--unpack): trying to overwrite '/lib/udev/rules.d/71-nvidia.rules', which is also in package nvidia-kernel-common-390 390.48-0ubuntu3 ErrorMessage: trying to overwrite '/lib/udev/rules.d/71-nvidia.rules', which is also in package nvidia-kernel-common-390 390.48-0ubuntu3 InstallationDate: Installed on 2016-05-19 (706 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) Python3Details: /usr/bin/python3.6, Python 3.6.5, python3-minimal, 3.6.5-3 PythonDetails: /usr/bin/python2.7, Python 2.7.15rc1, python-minimal, 2.7.15~rc1-1 RelatedPackageVersions: dpkg 1.19.0.5ubuntu2 apt 1.6.1 SourcePackage: nvidia-graphics-drivers-340 Title: package nvidia-340 (not installed) failed to install/upgrade: trying to overwrite '/lib/udev/rules.d/71-nvidia.rules', which is also in package nvidia-kernel-common-390 390.48-0ubuntu3 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-340/+bug/1767116/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
