apt-get 실행 시 저장소 찾지 못하는 오류 해결

ubuntu에서는 특정 저장소를 통해서 소프트웨어를 배포한다.
apt-get 명령어를 이용하여 소프트웨어 패키지를 다운로드하게되는데
간혹 apt-get 명령어 실행시 다운로드 에러가 발생하는 경우가 있다.

기본저장소로 설정되어 있는 Kaist 서버가 죽은 경우인데,
소프트웨어 패키지를 읽어올 저장소의 위치를 Daum으로 변경하여 간단히 해결 할 수 있다.

/etc/apt/ sources.list 파일을 열어서 아래와 같이 주소를 수정하면 된다.

우선 Terminal을 열고 아래와 같이 입력 한다.

$sudo gedit /etc/apt/sources.list

gedit 가 열리면 아래와 같이 내용을 수정한다.

ubuntu 버젼에 따라 상기 파일의 내용이 조금 달라진다.
(위의 예제는 9.04 jaunty 기준임)

파일 수정이 완료 되었으면 저장 후 gedit를 종료한다.

다시 터미널에서 아래와 같이 저장소를 update한 후 원하는 소프트웨어를 apt-get을 이용하여 다운로드 하면된다.

$sudo apt-get update
