문제의 시작

오라클 프리티어 인스턴스들을 너무 잘 쓰고 있는데, 오늘 갑자기 업데이트 중 에러가 나옵니다. 게다가 엄청 느려진 속도는 덤..

Cannot initiate the connection to security.ubuntu.com:80 (2620:2d:4000:1::19)라는 에러가 뜨는데..

어.. 찾아보니 우분투 서버 죽어서 그렇다고 합니다.

구글링을 해보니 아래 내용이 나오는데.. 저는 적용해도 오류가 나더라구요.

해결

위 블로그의 팁대로 초기화를 해봤으나, 문제가 해결되진 않았고, 제 경우 그냥 저장소 주소를 카카오로 변경했습니다.

오라클 프리티어의 경우 /etc/apt/sources.list 파일이 아래와 같이 되어있습니다.

첫번째 문구를 보면 뭐 유지가 안된다는거같은데, 일단 씌워봅니다(…?)

내용 다 지우고 아래 내용을 넣습니다.

재시도시 빠르게 받아옵니다. 업그레이드 되지 않은 패키지가 3개가 있다고 나오는데, 이건

apt install -y --only-upgrade [패키지명]으로 입력하면 됩니다.
