Docker容器安装vim失败解决方案

1.切换docker内apt-get镜像源为清华源

备份源：mv /etc/apt/sources.list /etc/apt/sources.list.bak
 执行新源

echo  "deb http://mirrors.tuna.tsinghua.edu.cn/debian/ buster main contrib non-free" >/etc/apt/sources.list
echo  "deb http://mirrors.tuna.tsinghua.edu.cn/debian/ buster-updates main contrib non-free" >>/etc/apt/sources.list
echo  "deb http://mirrors.tuna.tsinghua.edu.cn/debian/ buster-backports main contrib non-free" >>/etc/apt/sources.list
echo  "deb http://mirrors.tuna.tsinghua.edu.cn/debian-security buster/updates main contrib non-free" >>/etc/apt/sources.list

2.执行apt-get update,然后安装vim

apt-get update
apt-get install vim
3.检查是否成功

vim --help
