FROM ubuntu:jammy RUN echo "deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse" > /etc/apt/sources.list RUN apt update
我要安装软件
要先替换软件源
替换之后需要 apt update
但是貌似不行？

改成下面这样也不行
FROM ubuntu:jammy RUN apt install -y ca-certificates RUN echo "deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse" > /etc/apt/sources.list RUN apt update
也报错

所以这不久变成了先有鸡还是先有蛋的问题了吗？
我安装软件需要网络，需要使用网络需要 ca-certificate，安装 ca-certificates 需要网络？
要用源才行，docker中的apt是没有安装这个包的，是无法使用https源的httpapt-transport-https
而且你就一个仓库也不对，会有一些包缺失的，按照tuna官方文档，应该配置至少4个源 https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/
一个简单的shell脚本自适应ubuntu镜像：
source /etc/os-release
cat > /etc/apt/sources.list <<EOF
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ ${VERSION_CODENAME} main restricted universe multiverse
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ ${VERSION_CODENAME}-updates main restricted universe multiverse
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ ${VERSION_CODENAME}-backports main restricted universe multiverse
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ ${VERSION_CODENAME}-security main restricted universe multiverse
EOF
