From one of my hosts I can authenticate with ssh to GitHub, from another I cannot git#github.com: Permission denied (publickey).
I was having some issues from my Mac creating a new repo and pushing to it, I always got a permission denied error. However from my Linux host it worked fine.
I checked the repos for deploy keys (in case this was causing the issue), none of my repos had a deploy key set.
I checked the keys on GitHub and there was only one ssh key installed. I deleted this key and tested, as expected the repos from the Linux host could not connect, yet the Mac could still connect.
From the Mac:
ssh -T git#github.com Hi mcdent/blog1! You've successfully authenticated, but GitHub does not provide shell access. bash-3.2$
From Linux:
[mike#docker1 doing]$ ssh -T git#github.com git#github.com: Permission denied (publickey). [mike#docker1 doing]$
I'm puzzled as to how the Mac is still authenticating? I likely did have a repo called blog1 in the past but I certainly don't now.
Ideally I'd like to have a single key used on GitHub, which I can use with both my Linux and MacOS hosts.
Any pointers very welcome.
I'm puzzled as to how the Mac is still authenticating?
Then try a ssh -Tv git#github.com.
You will see which key file is accessed and used for this authentication.
It should be a private key whose public key is registered to your account.
Check your environment variables or git config --global / git config --system -l for anything including blog1.

I have a repo at GitHub. When cloning it in Linux using ssh it works fine:
> git clone git#github.com:henrikppersson74/frokenjennnie.git
Cloning into 'frokenjennnie'...
Enter passphrase for key '/home/----/.ssh/id_rsa':
.
.
Reinitialized existing Git repository in /home/*
When doing the same thing in Windows PowerShell it doesn't work:
> git clone git#github.com:henrikppersson74/frokenjennnie.git
Cloning into 'frokenjennnie'...
git#github.com: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
I have copied my private and public SSH keys from Linux to my Windows machine and they are stored in my ~/.ssh/ as id_rsa and id_rsa.pub.
It seems to work when I try to access github.com with ssh from PowerShell:
> ssh git#github.com
Enter passphrase for key 'C:\Users\-----/\.ssh\id_rsa':
PTY allocation request failed on channel 0
Hi henrikppersson74! You've successfully authenticated, but GitHub does not provide shell access.
Connection to github.com closed.
This is the same answer I get when doing this in Linux. I guess this means the my SSH-key par is ok?
When working in Eclipse in Windows, using the "Git Repositories" view it works fine to clone the same repo.
Previously I created new SSH keys in the PowerShell and copied the public one to GitHub, but with the same result.
My ~/.ssh/config file lookes like this:
Host github.com
HostName github.com
IdentityFile ~\.ssh\id_rsa
User git
ForwardAgent yes
I am using Git version:
> git --version
git version 2.28.0.windows.1
Unfortunately I get no extra information from using the --verbose flag:
> git clone git#github.com:henrikppersson74/frokenjennnie.git --verbose
Cloning into 'frokenjennnie'...
git#github.com: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
It doesn't help to add the key to the ssh-agent:
> ssh-add C:\Users\-----\.ssh\id_rsa
Enter passphrase for C:\Users\-----\.ssh\id_rsa:
Identity added: C:\Users\------\.ssh\id_rsa (C:\Users\-----\.ssh\id_rsa)
> git clone git#github.com:henrikppersson74/frokenjennnie.git --verbose
Cloning into 'frokenjennnie'...
git#github.com: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
Could my old keys be cashed somewhere?
Does anyone have any idea about why I am not able to clone my repo in Windows PowerShell? I would be so grateful for some help.
The problem was that my %HOME% environment variable was set to the wrong location. When I changed it back to C:\Users\<userid> it worked like charm. Apparently SSH first looks for a key in %HOME%\.ssh\, then for en entry in %HOME%\.ssh\config\ and last it uses the keys added to the ssh-agent.
I have one project on Gitlab and I worked with it for the last few days!
But after a few days it all went off! I added my home PC ssh key in Gitlab project setting, but now I want use git pull for receive new changes in my home PC show me this error:
10:47 AM Update failed
Permission denied (publickey).
Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
10:47 AM Update canceled

How can I fix it?
GitHub isn't able to authenticate you. So, either you aren't setup with an SSH key, because you haven't set one up on your machine, or your key isn't associated with your GitHub account.
You can also use the HTTPS URL instead of the SSH/git URL to avoid having to deal with SSH keys. This is GitHub's recommended method.
Further, GitHub has a help page specifically for that error message, and explains in more detail everything you could check.
I know this problem. After add ssh key, add you ssh key to ssh agent too (from official docs https://help.github.com/articles/generating-ssh-keys/)
ssh-agent -s
ssh-add ~/.ssh/id_rsa
After it, all work fine, git can view proper key, before couldn't.
I have done the following steps to setup ssh deployment keys with our git repo for it to be able to git pull without a username and password:
Note: I am on AWS EC2 / Ubuntu 14.04.3
Run ssh-keygen -t rsa -b 4096 -C "ownersEmail#gmail.com" these are then saved as id_rsa and id_rsa.pub in ~/.ssh/
The deployment public key (id_rsa.pub) is added on the GitHub online UI in the deployment keys section
The directory is already cloned in /var/www/ directory, this is working all good via HTTPS for pulling
Try sudo git pull git#github.com:ownersUsername/OurRepo.git and get the following error
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
Another Note: This repository is private under another users account.
Also, when I try ssh git#github.com I get:
Hi userName/Repo! You've successfully authenticated, but GitHub does not provide shell access.
Connection to github.com closed.
And the deployment key comes up as being used. Have been on this issue for greater than 4 hours now and any would would be very much appreciated, thanks.
The problem is you're using sudo, which runs the command as root, and it will try to use the root's keys not your user's keys.
What you want to do is:
give your user/group write access to /var/www
run the pull/clone as the user, not the root user.
When you do a git pull you don't need the link.
git pull <remote> <branch>
You need the full url for the clone command
sudo git clone git#github.com:ownersUsername/OurRepo.git
To test if your ssh key is good use this:
git fetch --all --prune
I have configured Jenkins on a Linux machine and my git repo is on an another Linux server. But when I try to give the URL of the repo to Jenkins I get the following error.
Failed to connect to repository : Command "git -c core.askpass=true ls-remote -h ssh://user#ip/~/export1 HEAD" returned status code 128:
stdout:
stderr: Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
What could be the cause for this?
I have seen that both the systems' rsa key is present in each other's .ssh/known_hosts folder.
I am able to pull or clone code from the repo to a folder in Jenkins system as well. So why is Jenkins not able to take it?
I have also tried the URL user#ip:/fullpath/to/repo
You need to make sure Jenkins is running as the right user (the one who has the keys in ~/.ssh/id_rsa(.pub)
That user might not be the same as the one used in the ssh url: user#ip means you are connecting to ip using an account which has your public key in ~user/.ssh/authorized_key.
So the Jenkins process must be run by an account which has the private and public key, whose public key is in ~user/.ssh/authorized_key on the git server side.
And that account should have done (only once) an ssh-keyscan -H ip >> ~account/.ssh/known_hosts before any ssh attempt, in order to record the git server ip as a known host.
Does it being a bare repo make any difference or change in the URL?
No. The .git at the end of the bare repo folder is optional when used as an url.
Further to #VonC's reply, you can also use the Credentials plugin to define a set of credentials on your Jenkins master that your Jenkins job uses to access your Git repo. This allows you to run Jenkins itself as a different user from there one that has access to the Git repo.
The main problem was the security of the systems. I hadnt checked the authentication mechanisms on my server. The password authentication to the git server was causing the problem because the jenkins machine tries to directly fire a ls-remote to the path. When you do the same thing on the terminal you will be prompted for a password and then itl accept. When I set the password authentication and UsePAM to no and enabled the RSA authentication, pubkey authentication and authorised key setting to yes in the sshd_config file, and restarted, it was able to access the repo and I dint get this error.
I installed Gitlab on my Ubuntu successfully(gitlab.domain.com), on a client PC I installed Git (windows 7), then run Git Bash to generate SSH keys with command: ssh-keygen -t rsa -C "username#domain.com" to create private/public keys on C:\Users\AccountName.ssh
Then, add public key to profile on installed gitlab. Then can clone/push on Git Bash.
However, I can not reproduce this on other PCs, I tried some PCs, created new users, new ssh keys...
but always encounter that error "The remote end hung up unexpectedly", sometimes can clone but also get that error when pushing.
I can only clone/push on first PC. I'm so confused, don't know what I missed. I'm trying to get my team on Git
Thanks a lot for any advice
Make sure you are pointing it at the correct git server. Also - login on your Jenkins server (Under the jenkins user) and ssh to git#your-git-server and make sure to select 'yes' to add the server to your known hosts.
I had the same error and it was an access-level problem :
my user only had guest access to my project so it wasn't able to clone it. I changed the access level to developper and it solved my problem
