bash：sudo：在 debian jessie 上找不到命令[关闭]

Question

我最近在我的笔记本电脑上安装了 Debian 8，当我尝试使用“sudo”时，它响应为

bash: sudo: command not found`

然后我运行了以下命令

/usr/bin/sudo

我收到以下错误

bash: /usr/bin/sudo: No such file or directory

之后，当我尝试使用

apt-get

安装它时，我得到了这个

Answer 1

我找到了！ /etc/apt/source.list 中的 source.list 为空！对于有同样问题的人：转到下面的链接并找到您所在的国家/地区并将链接复制到 source.list 或搜索 debian 源列表生成器 debian.org/mirror/list-full

Answer 2

尝试“sudo su”来获取 root 访问权限，而不是仅尝试“sudo”。希望有帮助
