【教程】debian 换成阿里云的源
刚入 debian 的坑。。。目前是 debian9(stretch)+gnome3。刚开始装时候是 dvd 版安装，源都是 dvd 的本地目录。。。于是果断换源。。。打开阿里云镜像站：https://developer.aliyun.com/mirror/。找到”debian” 那一行，点帮助就可以看到源的用法了：
终端运行命令：
sudo gedit /etc/apt/sources.list
（如果没有 sudo 命令就用 su 命令）
用以下文字覆盖文件内容：
deb-src http://mirrors.aliyun.com/debian/ stretch main non-free contrib
deb http://mirrors.aliyun.com/debian-security stretch/updates main
deb-src http://mirrors.aliyun.com/debian-security stretch/updates main
deb http://mirrors.aliyun.com/debian/ stretch-updates main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch-updates main non-free contrib
deb http://mirrors.aliyun.com/debian/ stretch-backports main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch-backports main non-free contrib
保存，在终端执行命令：
sudo apt-get update
解决There is no public key available错误
W: There is no public key available for the following key IDs:7638D0442B90D010
W: There is no public key available for the following key IDs:7638D0442B90D010
W: There is no public key available for the following key IDs:9D6D8F6BC857C906
但是，老蒋这边更新源之后，执行升级命令还出现错误。下面的key等于上面的key.
apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 7638D0442B90D010
apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 7638D0442B90D010
apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 9D6D8F6BC857C906
Docker ubuntu apt-get更换国内源解决Dockerfile构建速度过慢
在Dockerfile中添加如下两句代码：
RUN sed -i s@/archive.ubuntu.com/@/mirrors.aliyun.com/@g /etc/apt/sources.list && apt-get clean
更新apt源的Dockerfile如下：
FROM ubuntu:latest
MAINTAINER kk "kk@qq.com"
RUN sed -i s@/archive.ubuntu.com/@/mirrors.aliyun.com/@g /etc/apt/sources.list && apt-get clean && apt-get update
出现The following packages have unmet dependencies问题
这个自动修复依赖，有时候管用
If sudo apt-get install -f <package-name> doesn't work, try aptitude:
sudo apt-get install aptitude
sudo aptitude install <package-name>
