upgrading from RHEL 7.3 to RHEL 7.6

Hello--new to Linux and your patience is greatly appreciated.

I issued the command below in order to go from RHEL 7.3 to RHEL 7.6 (in preparation for RHEL 8.0)

sudo yum update -y

and it failed, giving a transaction check error with the following messages:

file /usr/lib64/vdpau from install of mesa-filesystem-18.0.5-4.el7_6.x86_64 conflicts with file from package nvidia-375.20-x86_64.el7.1.x86_64

Any ideas on what is causing this and how to fix it? Thank you--Nina
