This issue can be taken care of by installing yum-plugin-elrepo from ELRepo.

Akemi,

Thank you for your help.  I actually had already installed yum-plugin-elrepo,
and that was
apparently part of the problem.   When I do an update with this repo active
kmod-nvidia-
430.40-2.el7_7.elrepo.x86_64.rpm is the rpm that is set to be installed which
does not work
because I an running Centos 7.6.   When I installed kmod-nvidia-430.40-
1.el7_7.elrepo.x86_64.rpm instead of doing an update everything worked
perfectly.

Looks like the elrep repsitory may have a problem with this update.

What kernel are you running? Please show the output from:

rpm -q kernel
uname -a

yum-plugin-elrepo is designed to mask kmod packages from the yum 
transaction when the required kernel from those packages is not 
available to yum. In order for the yum-plugin-elrepo to work correctly, 
all kernels should be available. Unfortunately, because of the 
differences between RHEL and CentOS, whereby RHEL makes ALL packages 
continuously available whereas CentOS repositories ONLY contain the 
latest point release and update packages, yum-plugin-elrepo may not work 
correctly on CentOS in some circumstances.

The workaround is to enable the CentOS vault repository so that all 
previous kernel packages are available to yum as they are on RHEL. See 
this bug:

https://bugs.centos.org/view.php?id=15476

Please try enabling the CentOS vault repo and see if that fixes your 
issue with yum.

Thanks,

Phil
