E: Unable to locate package vim

当执行docker exec -it b3771369a717 /bin/bash 进入docker的bash里面安装vim报错

root@1760b5b54639:/etc/mysql# apt-get install -y vim
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package vim

此时需要更新bash里面的apt-get的源

第一次更新

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

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

没有效果还是安装不上 再换一个源

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

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

安装成功。
