GitHub: Permission denied (publickey). fatal: The remote end hung up unexpectedly

Question

I have followed these instructions below to upload a project.

Global setup:

 Download and install Git
  git config --global user.name \"Your Name\"
         


        

Answer 1

For me, it worked like this:

In GitHub I changed the ssh link to https, and then gave the following commands:

$ git init
$ git remote add origin https:...
$ git add .
$ git commit -m "first commit"
$ git push origin master

Answer 2

For me the problem was the execution of clone via sudo.

If you clone to a directory where you have user permission ( /home/user/git) it will work fine.

(Explanation: Running a command as superuser will not work with the same public key as running a command as user. Therefore Github refused the connection.)

This solution requires a SSH key already to be set up: https://help.github.com/articles/generating-ssh-keys

Answer 3

Given that none of the answers here worked for me, I finally tracked down my issue connecting to Bitbucket (or Github, doesn't matter in this case) with ssh -vT git@bitbucket.org.

In my case, the failure was due to using a DSA key instead of RSA, and apparently my SSH client no longer allows that.

debug1: Skipping ssh-dss key /c/Users/USER/.ssh/id_dsa for not in PubkeyAcceptedKeyTypes

The solution was to add this to .ssh/config:

Host *
    PubkeyAcceptedKeyTypes +ssh-dss

This elegantly appends the ssh-dss key type to all existing accepted public key types and after this was done, git can now ssh into Bitbucket no problem.

Answer 4

I got a solution after a long time in tutorials.

I followed the github tutorial on this link -> https://help.github.com/articles/error-permission-denied-publickey and I was able to connect in every step. But when I was trying to git push -u origin master I got this error:

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

Please make sure you have the correct access rights

Thats how I`ve fixed it!! Go to the project directory using the Terminal and check it out

$git remote -v

You will get something like this:

origin  ssh://git@github.com/yourGithubUserName/yourRepo.git (fetch)
origin  ssh://git@github.com/yourGithubUserName/yourRepo.git (push)

If you are using anything different then git@github.com, open the config file on git directory by typing the command:

vi .git/config

And configure the line

[remote "origin"]

url = ssh://git@github.com/yourGithubUserName/yourRepo.git

fetch = +refs/heads/*:refs/remotes/origin/

Answer 5

Yes, It's a public key Problem. I'm a windows user,and the page below help me resolve this problem.

Answer 6

My issue was that I was trying to give my ssh key a SPECIFIC NAME every time I entered ssh-keygen on my mac terminal.

I solved the issue by just leaving the name that "ssh-keygen" generates = id_rsa. You'll end up with 2 keys in your .ssh folder on a mac, id_rsa, which is your private key, and the id_rsa.pub, which is your public key. Then I copied and saved the code from id_rsa.pub into my GitHub account settings, and that was it. Problem solved.
