Gitlab ce ssh pupkey - linux

Hey Im in trouble with my gitlab server on Ubuntu 14.04 64Bit
Establish a connection via ssh is not working.
The connection to the server via ssh with the same keys works fine.
The key for github is saved at
/var/opt/gitlab/.ssh/authorized_keys
and begins with
command="/opt/gitlab/embedded/service/gitlab-shell/bin/gitlab-shell key-4",no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty ssh-rsa [...]
the auth.log gives the following message
input_userauth_request: invalid user git [preauth]
Connection closed by 139.13.201.xxx [preauth]
the output from ssh -vt

I ve found the following hint on gitlab faqs
https://github.com/gitlabhq/gitlab-public-wiki/wiki/Trouble-Shooting-Guide#ssh
But there is no /home/git directory.
[1] git user in passwd
git:x:998:998::/var/opt/gitlab:/bin/sh
Hope you can give me any advise.
Thanks for helping
[1]Edit

Oh, shame on me, I switched off PAM in the sshd_config, during some expirements with ssh and never switched it on.

The SSH troubleshooting is written assuming GitLab is installed with a git account in /home/git (and include a /home/git/.ssh/authorized_keys)
If that is not your case, but ssh still uses 'git', that means your GitLab config still references the default user git
# Uncomment and customize if you can't use the default user to run GitLab (default: 'git')
# user: git

Is there any workaround for the permission denied (publickey) error in google cloud?

I am currently doing the Build and Secure Networks in Google Cloud: Challenge Lab from Google Cloud Skills Boost. I finished challenge number 1-5, but got stuck in challenge number 6:
In the Compute Engine instances page, click the SSH button for the bastion host. Once connected, SSH to juice-shop.
After SSH to bastion, I typed ssh (IP address of juice-shop), but it results in Permission denied (publickey). error. I tried typing -v after the SSH command, and this is what shows up after executing:

Has the same problem occurred to anyone else, or does anybody have any solution to this problem? Any help would be appreciated, thank you.
Run this command in bastion SSH.
gcloud compute ssh juice-shop --internal-ip
after this keep empty in passphrase and press enter two times and press y in y/n.
and check your progress.

SSH into server Authentication Failed

Hi I 'm trying to SSH into a server from client (RHEL7) machine. I already added the clients public key (id_rsa.pub) to the servers authorized_keys file. I also added the servers fingerprint to my clients known_hosts file. When I try sshing, I used the -vvv flag to get some debug info and this is what I got (of course I put a fake IP in, and the returned SHA256 is fake):

Can anyone provide some insight on what I can do to get this working?
Looks like a permission issue in .ssh folder
Following commands to be run at the server to set the correct permission for the folders.
chmod 700 ~/.ssh/
chmod 600 ~/.ssh/authorized_keys

why ssh always ask me for passwords even I have set the public key in VPS?

I just order a VPS in Vultr, and want set to ssh without passwords. after configured the ssh key things, I think it should be work, but failed.
yes, I have multiple ssh configures like github, gitlab or some other things and this is the configure file
Host gitlab
HostName cd.i.foo.com

I think I spend lots of time here, it really maked me confused, thanks in advance for any help
ssh -v -v root#198.13.59.103 would not work, as it would default to id_rsa.
You need to test:
ssh -Tvv vultr
Only that "URL" (vultr) would be the equivalent of ssh root#198.13.59.103 -i ~/.ssh/id_rsa_vultr: it would find everything it needs in your ~/.ssh/config, under the Host vultr entry.
Doesn't look like it accepts an RSA-signed key.
Look at these lines:
debug1: Trying private key: /Users/xdguo/.ssh/id_dsa
debug1: Trying private key: /Users/xdguo/.ssh/id_ecdsa
debug1: Trying private key: /Users/xdguo/.ssh/id_ed25519
It's looking for a private key signed with DSA instead.
Try again and create a private-public pair signed with DSA instead. (No need to remove your other private key; you can have as many as you want of as many different types as you want on your machine.)

Permission denied (publickey) Git and AWS EC2

There are many similar questions and answers related to this authorization issue --- "Permission denied (publickey)". However, none of them works for my problem...
Here is my situation: I am using Amazon web server EC2 and my PC connects well with the server. For the next step, I was trying to install git on the server. The result which I was hoping to accomplish is updating the server-end when I push from local. But here the problem showed up: "Permission denied (publickey)"

One thing I am wondering is where should I put the public key exactly? There is one .ssh file for "validate server connection" already in the server, path: ~/.ssh and it works for me.
In terms of the ssh key for git, I created another .ssh folder inside the git folder, path: ~/home/git/.ssh. Which file does it look for during the connection? Though I've tried to put the public key into ~/.ssh, but still, it does not work...
I've been stuck there for so long time and really appreciated if someone can help me out! Workarounds to achieving "update as push" will also help me out!
One thing I am wondering is where should I put the public key exactly?
you have to put the public key on your git server under your account.
Which file does it look for during the connection?
you have to copy the ~/.ssh/id_rsa.pub to your git server account
