Trường hợp này các bạn có thể fix bằng cách:

1. Điều chỉnh lại Nameserver

nano /etc/resolv.conf

Nếu đã có nameserver nào rồi thì bạn hãy xóa đi, rồi thêm 2 dòng sau vào phía cuối:

nameserver 8.8.8.8
nameserver 8.8.4.4

Save file lại và Exit

2. Xóa cache

yum clean metadata
yum clean all

Vậy là xong.
