# 

/etc/resolv.conf 화일을 바꾸어도 안되고, /etc/apt/sources.list 에서 주소를 바꾸어도 안되고,,,

결국은, 아래 사이트 에서 제시한 것 처럼,

$ vi /etc/network/interfaces

# The primary network interface
auto enp0s9
iface enp0s9 inet static
address 10.11.12.11
netmask 255.255.255.0
network 10.11.12.0
gateway 10.11.12.1
broadcast 10.11.12.255
dns-nameservers 8.8.8.8 8.8.4.4

적색 표시된 것 처럼, dns-nameservers 8.8.8.8 8.8.4.4 를 추가한 후에 정상적으로 진행된다.

gateway 설정은 덤,

즐 ubuntu 하시길,,,
