풀이
1. Helm의 서명 키 추가

curl https://baltocdn.com/helm/signing.asc | apt-key add -

• Helm의 서명 키(signing key)를 다운로드하여 시스템의 APT 키 저장소에 추가
• Helm을 설치할 때 패키지의 무결성을 확인하기 위해 이 서명 키가 필요
• curl 명령어를 사용하여 Helm 서명 키를 다운로드하고, apt-key add를 사용하여 시스템에 추가

2. APT transport 설치

apt-get install apt-transport-https --yes

• APT가 HTTPS를 통해 패키지를 다운로드할 수 있게 하는 apt-transport-https 패키지를 설치
• Helm의 패키지 저장소는 HTTPS 프로토콜을 사용하므로, 이를 처리할 수 있는 도구가 필요

3. Helm 저장소 추가

echo "deb https://baltocdn.com/helm/stable/debian/ all main" | tee /etc/apt/sources.list.d/helm-stable-debian.list

• Helm의 공식 Debian 저장소를 시스템의 APT 소스 목록에 추가
• Helm을 설치하려면 이 저장소를 APT 패키지 관리자가 인식할 수 있어야 함
• tee 명령어를 사용하여 Helm의 패키지 저장소 정보를 /etc/apt/sources.list.d/에 추가

4. 패키지 목록 업데이트
   apt-get update

• APT 패키지 관리자가 새로운 저장소 정보를 인식하도록 패키지 목록을 업데이트
• Helm 저장소를 추가한 후, 새로운 저장소에서 사용할 수 있는 패키지 목록을 가져오는 과정

5. Helm 설치
   apt-get install helm

• apt-get install helm 명령어를 통해 Helm을 시스템에 설치
