[CentOS] Centos7.3-Mate

Hello All, 

I have this problem starting Centos7.3 - the official name escapes me at the moment. 
I often install Centos7 Minimal, then X Window System, then Mate desktop. 
This last step gives me trouble, and I have to run 
# yum groupinstall mate --skip-broken 

output: 
skipped packages: 
NetworkManager-I2tp 
ldns 
libreswan 
unbound-libs 
xl2tpd 

I realise this is probably an issue for EPEL or Mate. 

Happy hollidays 

J.
