Unable to SSH to instance

[Heng Yong Sheng]

Hi, 

I am unable to SSH into my instance and here is what I see on the serial console.

Does anyone know how to resolve this?

May 26 06:55:43 instance2 GCEGuestAgent[456]: 2021-05-26T06:55:43.5426Z GCEGuestAgent Info: Adding existing user myid to google-sudoers group.

May 26 06:55:43 instance2 GCEGuestAgent[456]: 2021-05-26T06:55:43.5622Z GCEGuestAgent Info: Updating keys for user myid.

May 26 06:55:43 instance2 GCEGuestAgent[456]: 2021-05-26T06:55:43.5623Z GCEGuestAgent Error non_windows_accounts.go:158: Error updating SSH keys for myid: open /home/myid/.ssh/authorized_keys.google: file exists.

Thanks.

Hi,

From the given logs, it seems like the error is from the guest agent[1]. if you could move the authorized_keys.google file out of /.ssh/ and to another temporary location for the user who is facing this error and try it again may resolve the issue .

Currently as the file is already available in the location, it is not allowing to create a temporary file to eventually update keys for the user. So maybe moving the authorized_keys.google file out of /.ssh/ and to another temporary location may help.

Please keep in mind to do this only for the user who is facing the error and not all the users.

Thanks for your suggestion.

I have actually went ahead to re-create a fresh instance for myself, but I will try this if the issue occurs again in the future. 

May I ask, how can I move the file out without having the ability to ssh in?

Hello, 

You can connect via serial console as indicated in this documentation [1].

Have a nice day!
