docker容器安装好Ubuntu18.04以后的种种问题

辛辛苦苦安装好docker以及Ubuntu18.04，在执行第一条命令

sudo apt-get update 

返回报错信息：

sudo command not found

好的呢，网上说修改一下源就行。那就键入命令

vi /etc/apt/source.list

我又得到一个惊喜：

vi command not found

所以，我就要安装这个vi

sudo apt-get install sudo

问题回到最初：我没有sudo (心态已经炸了)

最后尝试多种方案以后，
先在docker容器里面执行

cp /etc/apt/source.list /etc/apt/source.list.backup
rm /etc/apt/source.list

再回到宿主机执行(我的容器名字叫做nachos，自己替换为id或者容器名就行)

docker cp /etc/apt/source.list nachos:/etc/apt/source.list

再

apt-get update

就OK，最后慢慢安装sudo ,vim ,wget, yum啥子的
