I try to ssh from my local host to GCP cloud shell and get the error:
$ gcloud cloud-shell ssh --authorize-session
sign_and_send_pubkey: signing failed for RSA "/home/kossak/.ssh/google_compute_engine" from agent: agent refused operation
<USER>@<IP>: Permission denied (publickey).
ERROR: (gcloud.cloud-shell.ssh) [/usr/bin/ssh] exited with return code [255].
with debug option:

What I tried already:
- restarting ssh-agent on local machine
- rebooting my local machine and cloud shell
gcloud compute config-ssh (on both local machine and cloud shell) returned only WARNING: No host aliases were added to your SSH configs because instances have no public IP.- removing all ssh keys from GCP Compute => Metadata => SSH Keys
- renaming
~/.ssh and trying to connect again
ssh-add -l returns both of my keys: rsa (from gcp) and ed25519 (created manually)- permissions of
/home/kossak/.ssh are 700
- permissions of
/home/kossak/.ssh/google_compute_engine are 600
- connecting to another SSH server in my local network with a ssh key - works properly
- executing git commands with ssh key authorization (eg
git remote update) - works properly
I use:
- Linux Manjaro
- Google Cloud SDK 410.0.0
I can login to cloud shell from another host so the problem is probably with my computer. Anybody knows what's wrong or how to debug it?
Thank you for any advice.
