 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Don't know how to install it.

I was hit with the same issue.

You should be able to use: yum install xrdp --enablerepo=cr to get around this for now as the xorg-x11-server-Xorg(x86-64) = 1.20.1 packages should be available in the continuous release repo.
