I am install C7.5 on a nvidia unit and nvidia-detect tells me to use kmod-nvidia-390xx so I do the yum install and and after a long time I see this -> Processing Dependency: kernel(__drm_atomic_helper_crtc_duplicate_state) = 0xa5f3a170 for package: kmod-nvidia-390xx-390.87-2.el7_6.elrepo.x86_64 --> Processing Dependency: kernel(__drm_atomic_helper_crtc_destroy_state) = 0x00a9c70b for package: kmod-nvidia-390xx-390.87-2.el7_6.elrepo.x86_64 --> Processing Dependency: kernel(__check_object_size) = 0x88db9f48 for package: kmod-nvidia-390xx-390.87-2.el7_6.elrepo.x86_64 --> Processing Dependency: kernel(___ratelimit) = 0x155f4108 for package: kmod-nvidia-390xx-390.87-2.el7_6.elrepo.x86_64 --> Processing Dependency: kernel >= 3.10.0-957.el7 for package: kmod-nvidia-390xx-390.87-2.el7_6.elrepo.x86_64 ---> Package nvidia-x11-drv-390xx.x86_64 0:390.87-1.el7_5.elrepo will be installed Packages skipped because of dependency problems: kmod-nvidia-390xx-390.87-2.el7_6.elrepo.x86_64 from elrepo nvidia-x11-drv-390xx-390.87-1.el7_5.elrepo.x86_64 from elrepo I have also tried --skip-broken and get the same result as above. have I missed something ? This has always working in the past. Thanks, Jerry
