12.04버전 쓰는데 apt-get 업데이트 할 때 오류가 납니다.ㅠ

12.04버전이 설치되어 있는 서버인데요;

프로그램을 새로 설치할게 있어서 설치를 하는데 몇 개의 dev 패키지를 추가로 설치해야하길래

설치를 하려고 해당 패키지를 apt-get 커맨드로 설치를 시도했습니다.

근데 오류가 뜨면서 설치가 진행되지 않더라구요.

그래서 오류 문구를 구글링해서 해결방법을 찾는데

apt-get update를 시도하라고 대부분이 나와있더라구요.

그래서 했는데 connection failed 라면서 아래 첨부된 것처럼 대부분이 오류가 생깁니다.ㅠ

왜그럴까요…

저도 궁금합니다.
왜 에러가 날까요?

제껀 친구집 PC에
깔아둔
데스크탑판 12.04 LTS 입니다.

소프트웨어센타를 구동시켜
그래픽환경에서 어떤 프로그램을
깔려고 클릭했더니 한참이 지나도
설치가 안되길래…

옵션에서 패키지를 받아오는서버를
'대한민국’에서 '주서버’로 변경했어요.

그러니깐 제가 설치하려했던
프로그램이 무사히 설치되더라구요,

위 경험에서 전 생각하기를
‘대한민국’ 의 동기화 서버들에
뭔지 모르지만 문제가 있을것이다 라고
생각하게 되었어요.

이 부분에 대해서 배경까지
상세히 설명해주실분 계신가요?

하여간 ‘주서버’ 로 변경후부터는
새패키지 판올림도 문제없이 잘되고,
다른 프로그램 설치도 잘 되고 있어요.

yogeebae님, yemharc님

설명 감사합니다^^!

지금은 해결되었는데요

위에 답변주신 분들 모두 감사하지만 제 경우에는 해결할 수 없는 방법이었구요.ㅠ

제가 의심했던건

문제가 있는컴이 서버인데 학교에서 수업용으로 사용하는 것이거든요.

그런데 얼마전부터 학교측에서 인터넷을 사용하기 위해서

보안 인증을 하도록 했습니다.

제가 쓰는 컴은 항시 사용하는 것이고 데스크탑(?)용 이니까

당연히 인증을 받아서 쓰고 있어서 서버까지 인증을 받아야 한다고 생각하지 않았는데

혹시나 해서 문제의 서버의 콘솔에서 학교 보안 인증을 받고

업데이트를 시도해 보았더니 아주 잘 되었습니다.ㅠㅠㅠ

(중간에 무한 로그인 화면이 나와서 짜증이 났었지만… 이건 x11 설정이 안맞아서 그런거더라구요.ㅠㅠ)

학교측의 보안 인증 때문에 접속이 안 되었던 것이더라구요…

지금은 기존에 쓰던 다음 ftp 서버로 접속 잘하고 업뎃도 잘하고 잘 쓰고 있습니다.

혹시나 학교나 기업에서 쓰고 계신 서버에서 문제가 된다면

보안인증 같은게 있나 잘 살펴보세요.ㅠ
