우분투(Ubuntu)에서 apt 저장소(repository)를 변경하는 방법

1. apt 저장소 확인

현재 사용 중인 저장소 목록을 확인합니다.

vim /etc/apt/sources.list

apt_sources_list

sources.list

2. 기존 저장소 백업

저장소를 변경하기 전에 현재 설정을 백업해두는 것이 좋습니다.

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

3. 새 저장소 설정

새로운 저장소 정보를 설정하려면 /etc/apt/sources.list 파일을 수정합니다.

• vim 명령어로 apt 저장소 변경(vim의 치환 가능을 이용하여 변경)

:%s/kr.archive.ubuntu.com/mirror.kakao.com/g

apt_sources_list

• sed 명령어로 apt 저장소 변경

sed -i 's/archive.ubuntu.com/mirror.kakao.com/g' /etc/apt/sources.list

sed -i 's/kr.archive.ubuntu.com/mirror.kakao.com/g' /etc/apt/sources.list

728x90

4. apt 저장소 업데이트

저장소 설정을 변경했다면 아래 명령을 사용하여 저장소 정보를 업데이트합니다.

apt-get update

이 명령을 실행하면 새로운 저장소에서 사용 가능한 패키지 목록을 가져옵니다.

5. 패키지 업그레이드 및 설치

저장소가 정상적으로 업데이트되었다면 패키지를 업그레이드하거나 새로운 패키지를 설치할 수 있습니다.

• 패키지 업그레이드

sudo apt upgrade

• 새로운 패키지 설치

sudo apt install 패키지이름

 

저장소 변경 후에는 새로운 패키지가 사용 가능하게 되고, 저장소가 제공하는 패키지를 설치, 업그레이드, 관리할 수 있습니다. 하지만 저장소를 변경할 때에는 신뢰할 수 있는 소스를 사용하도록 주의해야 합니다.
