E: Unable to locate package vim

提示找不到vim，需要更新apt-get

$ apt-get update

然後再執行install

$ apt-get install vim

這裡會發現現在很慢，可以安裝國內映象源

apt-get配置國內映象源

參考 https://www.cnblogs.com/river2005/p/8503238.html

備份映象源sources.list

$ mv /etc/apt/sources.list /etc/apt/sources.list.bak

新增新的映象源

echo "deb http://mirrors.163.com/debian/ jessie main non-free contrib" >> /etc/apt/sources.list
echo "deb http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list
echo "deb-src http://mirrors.163.com/debian/ jessie main non-free contrib" >>/etc/apt/sources.list
echo "deb-src http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list
 

然後再使用apt-get update
