当我用镜像地址替换 deb 源时：
deb http://mirrors.aliyun.com/debian/ buster main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ buster main non-free contrib
deb http://mirrors.aliyun.com/debian-security buster/updates main
deb-src http://mirrors.aliyun.com/debian-security buster/updates main
deb http://mirrors.aliyun.com/debian/ buster-updates main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ buster-updates main non-free contrib
deb http://mirrors.aliyun.com/debian/ buster-backports main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ buster-backports main non-free contrib
构建时显示错误Dockerfile，如下所示：
=> ERROR [ 4/15] RUN install_packages acl ca-certificates curl gzip libbsd0 libbz2-1.0 libc6 libedit2 libffi7 libgcc-s1 libgmp10 l 8.8s

为什么会发生这种情况？我应该怎样做才能避免这个问题？
答案1
你的 deb 源显示 Debian Buster ( oldstable)，但是看看Debian 软件包站点，似乎libicu67仅适用于 Debian Bullseye ( stable) 或 Sid ( unstable)。libreadline8包裹丢失情况看起来很相似。
您应该能够使用基于 Debian Bullseye 的基础映像在 Docker 中修复此问题。
