If you look up the procedure, you will find a lot of information, but since "information that can only be found there" and "information that can only be found here" are dispersed, I will summarize the information for myself.

For some reason, symlink of NetworkManager is create on the way, so do the following just in case
# systemctl disable NetworkManager
Removed symlink /etc/systemd/system/network-online.target.wants/NetworkManager-wait-online.service.
I'm doing setenforce 0 for SELinux, so I think it's okay,
I've updated everything, so I'll do it for the time being.
