注意点

容器内保证/etc/resolve中的nameserver指向可联网dns，本地路由器/公网dns

ubuntu

方法1：
sed -i 's#http://archive.ubuntu.com#http://mirrors.ustc.edu.cn#' /etc/apt/sources.list
sed -i 's#https://archive.ubuntu.com#http://mirrors.ustc.edu.cn#' /etc/apt/sources.list
方法2：
cp -a /etc/apt/sources.list /etc/apt/sources.list.bak
echo > /etc/apt/sources.list
echo "# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-backports main restricted universe multiverse

# 以下安全更新软件源包含了官方源与镜像站配置，如有需要可自行修改注释切换
deb http://security.ubuntu.com/ubuntu/ jammy-security main restricted universe multiverse
# deb-src http://security.ubuntu.com/ubuntu/ jammy-security main restricted universe multiverse

# 预发布软件源，不建议启用
# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-proposed main restricted universe multiverse
# # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-proposed main restricted universe multiverse" > /etc/apt/sources.list

#apt update 遇到了证书验证失败的问题，这是因为apt无法验证清华大学镜像站的证书。为了解决这个问题，可以尝试安装ca-certificates包或者手动更新apt源列表，将清华大学镜像站的源更改为使用http协议而不是https协议。上面是更新后的apt源列表，已将所有源改为使用http协议。这样可以避免证书验证问题。
sed -i s/https/http/g   /etc/apt/sources.list
apt update

alpine

sed -i 's/dl-cdn.alpinelinux.org/mirrors.ustc.edu.cn/'  /etc/apk/repositories
apk  update
