Ubuntu 让用户获得root权限（附修复I have no name !；sudo: unknown uid 1000: who are you?）

修复：修改/etc/passwd 文件，把用户ID修改为 0，会报错：I have no name !；sudo: unknown uid 1000: who are you?

重启长按shift，进入recovery mode，选择root shell

mount -o rw,remount /vim /etc/passwd

改回去

修改/etc/sudoers 文件

vim /etc/sudoersroot ALL=(ALL) ALLyouruser ALL=(ALL) ALL
