[Solved] nginx depends libssl1.1 ( = 1.1.1) but it is not installable

DockerFile 빌드할 때 nginx: depends: libssl1.1 ( = 1.1.1) but it is not installable 에러가 났다

 

echo "deb http://security.ubuntu.com/ubuntu focal-security main" | tee /etc/apt/sources.list.d/focal-security.list \
apt-get update \
apt install libssl1.1 \

우분투 소스를 추가해서 강제로 libssl1.1 설치
