Getting permission denied (public key) on gitlab

问题:

My problem is that I can't push or fetch from GitLab. However, I can clone (via HTTP or via SSH). I get this error when I try to push :

Permission denied (publickey) fatal : Could not read from remote repository

From all the threads I've looked, here is what I have done :

• Set up an SSH key on my computer and added the public key to GitLab
• Done the config --global for username and email
• Cloned via SSH and via HTTP to check if it would resolve the issue
• Done the ssh -T [e-mail] command

Right now I want to punch my computer. If you have any insight about how to resolve my issue, it would be greatly appreciated.

I found this after searching alot. It will work perfectly fine for me.

1. Go to "Git Bash" just like cmd. Right click and "Run as Administrator".
2. Type ssh-keygen
3. Press enter.
4. It will ask you to save the key to the specific directory.
5. Press enter. It will prompt you to type password or enter without password.
6. The public key will be created to the specific directory.
7. Now go to the directory and open .ssh folder.
8. You'll see a file id_rsa.pub. Open it on notepad. Copy all text from it.
9. Go to https://gitlab.com/profile/keys .
10. Paste here in the "key" textfield.
11. Now click on the "Title" below. It will automatically get filled.
12. Then click "Add key".

Now give it a shot and it will work for sure.

Step 1: Added a config file in ~/.ssh/ folder which looks like

   User git
   Hostname gitlab.com
   IdentityFile ~/.ssh/id_rsa_gitlab
   TCPKeepAlive yes
   IdentitiesOnly yes

Step 2: Just clone the git repo WITHOUT sudo.

回答3:

make sure you are not running sudo git clone [e-mail]:project/somethiing.git, otherwise ssh will look in /root/.ssh instead of the key you uploaded ~/.ssh/id_rsa

回答4:

I think the simple solution is to add private key to authentication agent (if your key is not ~/.ssh/id_rsa),

ssh-add ~/.ssh/<your private key>

You basically let the ssh-agent take care of it.

Additionally, you can add it permanently.

In my case, it wasn't a gitlab problem, but a sshd configuration one. The ssh server didn't allow connection except for a list of users. The user git, the one connecting remotely to gitlab, wasn't in that list. So, check this before anything else.

You can check your ssh server configuration in /etc/ssh/sshd_config. If you have a line with the option AllowUsers, add git to it:

AllowUsers user1 user2 user3 git

I have gitlab running with docker, this is what I did to fix my problem.

Found that inside docker /var/log/gitlab/sshd/current there were multiple occurences of a message:

Authentication refused: bad ownership or modes for file /var/opt/gitlab/.ssh/authorized_keys

After which I changed ownership of that file from 99:users to git:users with:

chown git:users authorized_keys

Go to the terminal and regenerate the ssh key again. Type ssh-keygen. It will ask you where you want to save it, type the path.

Then copy the public key to gitlabs platform. It usually starts with ssh-rsa.

回答8:

if you are in linux or macox , just try this in terminal:

ssh-add -l

if it return nothing, try this:

ssh-add

it must create identity in ~/.ssh/id_rsa

after retry :

ssh-add -l

it must return your identity, so after retry to clone , it's must work

NB: don't forget to add your ssh key in your profile gitlab

thanks

I solved like this..

Generated a key for Windows using this command:

ssh-keygen -t rsa -C "[e-mail]" -b 4096

but the problem was that after running this command, it popped a line: "Enter file in which to save the key (/c/Users/xxx/.ssh/id_rsa): " Here, I was giving only file name because of which my key was getting saved in my pwd and not in the given location. When I did "git clone ", it was assuming the key to be at "/c/Users/xxx/.ssh/id_rsa" location but it was not found, hence it was throwing error.

At the time of key generation 2 files were generated say "file1" & "file1.pub". I renamed both these files as

file1 -> id_rsa 

and

file1.pub -> id_rsa.pub

and placed both in the location "/c/Users/xxx/.ssh/"

I added my ~/.ssh/id_rsa.pub to the list of known SSH Keys in my GitLab settings https://gitlab.com/profile/keys. That solved the problem for me. :-)
