无法“sudo”任何内容。任何命令都会返回帮助消息

今天更新 Ubuntu 16.04.3 系统后，我无法以非特权用户身份使用 sudo 运行任何命令，也无法以 root 身份运行相同的命令。每次“sudo”调用都只会返回一条帮助消息。

没有损坏的数据包，没有未配置的数据包，系统日志中没有奇怪的日志错误。SUDO 包已重新安装。没有任何帮助。请问，有人能帮忙吗？

SU 命令运行良好。SUDOERS 文件看起来正常。

运行alias。查看 是否有别名sudo。另外，尝试set | grep sudo查看那里是否有任何内容。

如果发现任何内容，请在~/.bashrc和~/.profile中查找别名或函数覆盖sudo。
