Why can't I do yum upgrade in centos 7 minimal?

Question

CentOS

Just installed a fresh system, climbed into

/etc/sysconfig/network-scripts/ выбрал ifcfg-enp2s0

and set up the network. The Internet works, IPs are pinged, but I can’t download anything, supposedly it doesn’t see the mirror.
I installed the system on this PC with the same settings very often, everything worked, and for the first time I see this. The image is fresh. How to remove it? The screen of the error will naturally be. And the screen of the network settings.

dns does not work, it tells you that the host cannot sober up
