visudo警告我有关语法错误，因此我没有进行任何更改就退出了。我决定在其中创建一个新文件/etc/sudoers.d。不幸的是，我没有对 manfile 概要给予足够的重视并发布sudo visudo -x /etc/sudoers.d/jupyter（正确的论点应该-f不是-x）。这导出了我的配置而不是创建新文件，最终结果是不再需要 sudo。
- 是否可以在不重新启动进入恢复模式的情况下恢复？
- 这种方法不适合我（使用鹦鹉螺）
- 另外，
visudo应该这样工作吗？ （不是讽刺，但其预期目的是保护用户，对吧？）Debian 联机帮助页指出它至少验证输入和输出文件是否相同。但显然它没有检查出口目的地是否合适？

sudo: parse error in /etc/sudoers.d/jupyter near line 1
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
答案1
如果你知道root密码那么你可以这样做
$ su root
# rm /etc/sudoers.d/jupyter
visudo将验证 sudo 文件如果处于编辑模式；你在导出模式下运行它...
