If I remember correctly the problem was that originally it was configured by anaconda with NetworkManager and ipv6 and yum worked well. Then I stopped and disabled NetworkManager service (the "network" service is already enabled by default, so no action for it) but I didn't remove all the IPV6 entries inside the anaconda-configured ifcfg-eno16780032 file in my /etc/sysconfig/network-scripts directory I also created a /etc/sysctl.d/noipv6.conf file with: net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 But I got the ipv6 problem when trying in general to run "yum update" After wiping ipv6 entries in ifcfg-xxx file all went well. Could it be that in some ifcfg-* files you still have any reference to ipv6? Also, I had to run systemctl restart network HIH, Gianluca
