데비안 10 - 가상 패키지 설치

가상 패키지 설치 문제를 해결하고 있습니다. 내 문제를 설명하는 데 사용된 dockerfile은 다음과 같습니다. Debian 10 기반 미러

FROM php:7.4.4-apache-stretch

RUN apt update
RUN apt-get install wget lsb-release -y
RUN apt-get -y install apt-transport-https  ca-certificates curl
RUN wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/>
RUN sh -c 'echo "deb https://packages.sury.org/php/ $(lsb_release -sc) ma>
RUN apt-get update && apt-get install php7.4-cgi -y

php7.4-cgi가 가상 패키지라는 것을 알았습니다
