Witches' Sabbath with yum install and docker

After a major CentOS update, when I "oc cluster up" I get this:

Error: Minor number must not contain leading zeroes "01"

the usual "docker version mismatch" issue (go to hell OpenShift)

So I "yum install docker" and I get this:

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

I try "yum install docker --skip-broken" but I still get

Then I do yum list installed | grep docker

docker-ce.x86_64 18.01.0.ce-0.1.rc1.el7.centos @docker-ce-test

then "yum remove docker-ce.x86_64" and "yum install docker"


Installed:

and everything works again.


I used to love Docker, but since it was split in CE and EE they messed really hard. Too much greed for money and need to place expensive consultants.
