I'm still trying to get my Centos-7.5 box up to 7.6. I had hoped
that the recipe above would work for me, but it does not.

Attempting to do "yum erase kmod-nvidia" spews a long list of apparently
unrelated packages that will be purged along with it, so I didn't do that.
Trying the "yum install kmod-nvidia" (note that the 390xx package is 
no longer the latest one so I didn't specify that) attempts to install
a whole ton (or two) of other packages which fails with more conflicts.
I don't think I should try explicitly installing the 390xx package since
i already have (kmod-nvidia.x86_64           410.73-1.el7_5.elrepo    @elrepo"
installed. I further note that epel now has 410.93 available.

So, attempting to follow the instructions and deal with mesa-libEGL first, 
erasing it lists a bunch of things it will remove in addition, which I 
dont' much want to do (bunch of Gnome packages, among other things), and
"yum install libglvnd-egl" wants to install a whole long list of updates
but that fails because of failed dependencies.

so, without being able to do the prepration outlined in the original
posting, if I just do "yum update" I get a lot of text flowing by, and
it finally ends with some errors. here (below) is the last bit of that
output, I'm hoping it will mean something to someone who can offer helpful
suggestions. I wonder why it is trying to install kmod-nvidia 340.xx
when I already have 410 installed? And I could avoid the whole mess by
doing a fresh install, but doing a fresh install is a serious pain in the
fundament--it takes days to get everything reconfigured the way I want it.
