How to complete these updates

Try manually removing python3* then rerun.

I have the same problem..only with those two not updating none of the other updates work either, all I can do is manually update all the other packages and still have those two listed.  Seems a major Bug!

 yum remove  python36u-3.6.8-1.el7.ius.x86_64 
 yum -y update
yum -y install cmake3

yum remove  python36u-3.6.8-1.el7.ius.x86_64 
 yum -y update
yum -y install cmake3

I had the same issue and rcschaff helped me to get out this issue using the above commands.
