[CentOS] Centos 7 Yum conflict libicalss

Folks

My Centos 7 systems are all failing to update because of

Error: Package: orage-4.10.0-4.el7.x86_64 (@epel)

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


Is there something I should (not) be doing?
The command was:
   yum update
