如何以 root 身份修复空的 /etc/sudoers？

我做到了

root@masi:~# visudo -x /etc/sudoers
root@masi:~# exit
logout
masi@masi:~$ sudo apt-get install vim
>>> /etc/sudoers: syntax error near line 1 <<<

我得到这个是因为该文件现在是空的，仅包含{\n}.如果有人可以向我发送/etc/sudoersDebian 8.5 的默认文件，那就太好了。

我愿意

解决方案为 root by adonis' /etc/sudoers，我做了gedit /etc/sudoers

#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults    env_reset
Defaults    mail_badpass
Defaults    secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification
root    ALL=(ALL:ALL) ALL

# Allow members of group sudo to execute any command
%sudo   ALL=(ALL:ALL) ALL

# See sudoers(5) for more information on "#include" directives:

#includedir /etc/sudoers.d

完毕！
