我在 ubuntu 用户中使用了chmod a+x /etc/sudoers这让我后悔...
ubuntu@VM-250-150-ubuntu:~$ ll /etc/sudoers
-rw-rw--w- 1 root root 781 May 5 11:12 /etc/sudoers
然后我可以t use sudo`
ubuntu@VM-250-150-ubuntu:~$ sudo
sudo: /etc/sudoers is world writable
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
我没有 root密码，所以我尝试pkexec chmod 440 /etc/sudoers.d来修复它。
但它有另一个问题，我输入 ubuntu的密码：
ubuntu@VM-250-150-ubuntu:~$ pkexec chmod 440 /etc/sudoers.d

朋友们，你能不帮我重新安装吗？我很后悔....
我希望我的故事可以帮助别人。让t change the privilege of / etc optionally. It更好地使用sudo visudo或编辑/etc/sudoers.d中的文件。
