sudoing时要求密码的Google Cloud VM [英] Google Cloud VM when sudoing asks for password

问题描述

我一直在使用Google Cloud debian VM，使用sudo进行超级用户任务完全没有问题（sudo不需要输入密码）。

I've been working with a Google Cloud debian VM and had no problem at all doing super user tasks using sudo (sudo was not asking for password).

今天，我像往常一样通过SSH连接，当我尝试 sudo某物 时，它开始要求输入密码：

Today I connected via SSH as usual and when I try to sudo something it started asking for password:

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

[sudo] password for -----:

文档中不应要求输入密码，因为它已经通过SSL密钥身份验证。

According to the documentation it should not ask for password as is already SSL Key authenticated connection.

推荐答案

我自己解决了此问题。我为有类似问题的任何人发布了我遵循的步骤：

I have solved this issue by myself. I post the steps i've followed for anyone who has a similar problem:

1. 删除VM 实例保留


2. 创建了用于恢复目的的新VM实例。


3. 附加了旧的VM磁盘到新实例



4. 安装到/ mnt /

1. Deleted the VM instance preserving the disk.
2. Created new VM instance for recovering pruposes.
3. Attached the old VM disk to the new instance

4. Mounted into /mnt/

# mount /dev/sdb1 /mnt/

将root更改为已挂载的分区

Change root to mounted partition

# chroot /mnt/

现在根据需要编辑sudoers文件以及用户密码和组

卸载磁盘

Now edit the sudoers file and the user password and group as needed

Unmount the disk

# umount /dev/sdb1

断开连接磁盘，删除恢复实例，然后使用相同的磁盘重新创建旧的VM

deattach the disk, delete the recovery instance, and recreate the old VM with the same disk
