原因分析：
这个错误表明你使用的操作系统版本，即 Debian 8 (jessie) 已经停止支持并已归档，因此官方软件源已经关闭。
所以更新操作系统包列表时就会遇到 404 错误。

解决方案：
如果要继续使用这个操作系统版本，你需要使用归档的 Debian 镜像源来更新包列表。
你可以在 /etc/apt/sources.list 文件中添加以下内容，指定归档源地址（直接执行一下命令即可）
 

#备份原文件
mv /etc/apt/sources.list /etc/apt/sources.list.bak
#添加源地址
echo "deb http://archive.debian.org/debian/ jessie main" >>/etc/apt/sources.list
echo "deb-src http://archive.debian.org/debian/ jessie main" >>/etc/apt/sources.list

 重新安装

root@b258a4f121b3:/# apt-get update
# 注意update执行完了之后可能还是会有报错，不过已经可以执行下面的安装语句了
root@b258a4f121b3:/# apt-get install -y vim
