【debian】debian12用户名不在 sudoers文件中的解决

终端输入su回车，输入 root 密码，回车，切换到 root 用户

打开 sudoers 文件：vi /etc/sudoers
找到 # Allow members of group sudo to execute any command
在 %sudo ALL=(ALL:ALL) ALL 下面添加 
yonghumigndavid ALL=(ALL:ALL) ALL
yonghumigndavid 为前面无法执行 sudo 命令的用户名
最后执行权限
pkexec chmod 440 /etc/sudoers
pkexec chmod 440 /etc/sudoers.d/README
pkexec chmod 440 /etc/sudoers.d
看到下面可以正常使用sudo
oot@debian:/home/debian# pkexec chmod 440 /etc/sudoers
root@debian:/home/debian# pkexec chmod 440 /etc/sudoers.d/README
root@debian:/home/debian# pkexec chmod 440 /etc/sudoers.d
root@debian:/home/debian# exit
exit
debian@debian:~$ sudo
