Ubuntu apt-get 오류시 대처법

우분투를 처음 설치하고 apt-get을 이용해 필요한 패키지를 설치하려고 하면,

가끔 아래와 같은 에러를 찍찍 뱉으며 안될때가 있다.

예를 들어 설치하려는 패키지가 vim 이라면

package vim is not available

the program vim can be found in the following packages

등등인데...

이는 apt-get 실행 시 저장소에서 패키지를 찾지 못해 발생하는 오류다.

기본 설치시 설정되어 있던 서버가 죽은 경우인데

이럴땐  패키지 저장소 주소를 daum의 ftp 서버로 변경해주면 된다.

(http://kr.archive.ubuntu.com -> http://ftp.daum.net/ubuntu)

귀찮다 싶으면 아래의 파일을 받아 변경해도 좋다. (우분투 12.04 기준)

※ 우분투 9.x 버전대의 구버전 같은 경우는 구 릴리즈 버전으로 변경하자.

(http://old-releases.ubuntu.com/ubuntu/)

sources.list

직접 수정하겠다면, 아래와 같이 설정 파일을 열어 수정해주자.

# vi /etc/apt/sources.list

vi의 치환기능을 이용해도 된다
