debian为什么安装不了任何软件，网友提供的系统

dd后的系统什么软件都不能安装，要怎么设置，好像是连接不上源的问题，

都没有vi等文本编辑器，我怎么换

只推荐在lxc子系统中操作。

sed -i "s/10.211.55.2:8000/debianbase/mirrors.aliyun.com/debian/g" /etc/apt/sources.list

安装这个就是为了安装pve,其他什么桌面的没有需求啊，只要桌面我用docker多美，还不用重新DD安装系统

docker不能当“虚拟机”用。它是开发用的。更像APP容器。

有没有只安装pve的脚本

啥意思，这不就是live pve吗

你把里面的lxc删掉不就是一个pve吗
