여기서 해결했다.

해결방법
$ vi /etc/network/interfaces 를 열고
dns-nameservers 8.8.8.8 8.8.4.4 를 추가.
esc + :wq!로 저장 후 닫기
$ vi /etc/resolv.conf 를 열고
nameserver 8.8.8.8
nameserver 8.8.4.4
를 추가

여기서 작성후 can't open file for writing 에러를 만나는 경우가 있는데 그러면 다음과 같이 입력하면 된다.

해결방법
$ sudo vi /etc/network/interfaces 를 열고
dns-nameservers 8.8.8.8 8.8.4.4 를 추가.
esc + :wq!로 저장 후 닫기
$ sudo vi /etc/resolv.conf 를 열고
nameserver 8.8.8.8
nameserver 8.8.4.4
를 추가

vi 앞에 sudo 붙이면 된다.

저거 하고 나니 스턱 걸린 것처럼 기다렸다가 안되던 기존 상황에서 뭔가 다운로드가 확실히 된다는걸 느낀다.

결론

해당 방법 올려주신 분 감사합니다.
