就像这家伙,当我尝试添加 ssh 密钥时,我开始收到一条错误消息:
Supplied fingerprint does not match current metadata fingerprint
当我尝试将密钥添加到
- 特定虚拟机实例的详细信息(使用 Web 界面)
- 共享元数据(使用 Web 界面)
我也不知道Permission denied (publickey).
是否可以使用username@instance
或username_mycomp_com@instance
登录。我和我所有的同事都无法再使用 ssh web 登录,这意味着我们已经被锁定在自己的服务器之外了!
我只能将此归因于运行gcloud compute os-login ssh-keys add
命令,它的影响似乎比它所说的还要大。
可能影响此问题的其他命令
gcloud compute ssh
$ gcloud compute ssh dev-mycomp-no

在指南中看到这个。假设这将使额外的登录方式。现在回想起来,我根本不知道这有什么用。

myuser@ubuntu
答案1
禁用 os-login 后我可以再次登录:
gcloud compute instances add-metadata dev-diffia-no --metadata enable-oslogin=FALSE
答案2
我在启用 OS Login 时遇到了类似的问题,我的密钥被旧的 debian jessie 实例拒绝。
症状如下:
Permission denied (publickey)
命令行上出现以下错误消息Using OS Login user
,Received malformed response from server
模块日志中的错误消息nss_oslogin
。
解决方案是从适当的存储库更新以下软件包:
- google-compute-engine
- google-compute-engine-oslogin
- python-google-计算引擎
- python3-google-计算引擎
前:
# dpkg -l | grep google
ii google-cloud-packages-archive-keyring 1.2-1 all Contains GPG signing key for Google Cloud Packages
ii google-cloud-sdk 253.0.0-0 all Utilities for the Google Cloud Platform
ii google-compute-engine 2.5.2-4 all google-compute-engine transitional package
ii google-compute-engine-init-jessie 2.1.3-0.1503598199 amd64 Google Compute Engine Linux initialization scripts
ii google-compute-engine-jessie 2.5.2-0.1502923259 all Google Compute Engine
ii google-compute-engine-oslogin 1.0.2-1+deb8 amd64 Google Compute Engine OS Login
ii google-config-jessie 2.1.2-0.1484936429 amd64 Google Compute Engine Linux guest configuration
后:
# dpkg -l | grep google
ii google-cloud-packages-archive-keyring 1.2-1 all Contains GPG signing key for Google Cloud Packages
ii google-cloud-sdk 253.0.0-0 all Utilities for the Google Cloud Platform

ii google-compute-engine-oslogin 1.4.3-1+deb8 amd64 Google Compute Engine OS Login

ii python3-google-compute-engine 2.8.16-1 all Google Compute Engine python library for Python 3.x.
为了连接到此实例以执行更新,您需要通过设置enable-oslogin=FALSE
实例的元数据来暂时禁用 OS Login如@oligofren 的回答所述。
然后确保它存在于/etc/apt/sources.list.d/google-cloud.list
(可能还有其他行):
deb http://packages.cloud.google.com/apt google-compute-engine-jessie-stable main
并执行更新:
# sudo apt install --reinstall google-compute-engine google-compute-engine-oslogin python-google-compute-engine python3-google-compute-engine
然后您可以为该实例重新启用 OS Login。
