1. 宿主机在etc/apt/下创建一个haha的文件夹
2.宿主机将haha文件夹映射到容器的虚拟系统中etc/apt/
3. 此时，可以在宿主机和容器虚拟机中同步创建和删除文件
4. 将宿主机中的source.list文件同步到容器浏览器中。
4.1 更新前容器虚拟机中的更新源
4.2 同步替换后的更新源
4.2.1 宿主机将sources.list拷贝到同步文件夹
4.2.2 容器虚拟机从同步文件夹中将sources.list拷贝到对应位置，覆盖掉原来的sources.list
4.2.3 容器虚拟机更新源
apt-get update
报错：Is the package apt-transport-https installed?
安装：apt-get install apt-transport-https 依然报同样的错
报错：Unable to locate package apt-transport-https
原因：sources.list 问题，换成清华园的sources.list即可，直接更新。
