GIT push: permission denied (public key)

问题:

GIT: I'm trying to push a file to a repo of a friend but errors on public key.

git push origin testbranch
Permission denied (publickey).
fatal: Could not read from remote repository.

Where and how do we define public / private keys?

git remote -v returns:

origin  [e-mail]:Sesamzaad/NET.git (fetch)
origin  [e-mail]:Sesamzaad/NET.git (push)

any help is appreciated.

I was facing same problem, here is what I did that worked for me.

Use ssh instead of http. Remove origin if its http.

git remote rm origin

Add ssh url

git remote add origin [e-mail]:<username>/<repo>.git

Generate ssh key inside .ssh/ folder. It will ask for path and passphrase where you can just press enter and proceed.

cd ~/.ssh
ssh-keygen

Copy the key. You can view your key using. If you hadn't specified a different path then this is the default one.

cat ~/.ssh/id_rsa.pub

Add this key to your github account. Next do

ssh -T [e-mail]

You will get a welcome message in your console.

cd into to your project folder. git push -u origin master now works!

I just had to deal with this issue. @user3445140's answer helped me, but was much more than I needed to do.

1. cat ~/.ssh/id_rsa.pub
2. copy the key, including the "ssh-rsa" but *excluding your computer name at the end*
3. Go to: https://github.com/settings/ssh
4. Add your SSH key

This worked for me.

first of all, remove current remote :

git remote rm origin

second, add remote through HTTPS but git@xxx :

git remote add origin https://github.com/Sesamzaad/NET.git

then push has worked for me :

git push origin master

None of the above solutions worked for me. For context, I'm running ubuntu, and I had already gone through the ssh-key setup documentation. The fix for me was to run ssh-add in the terminal. This fixed the issue.

I am running Ubuntu 16.04

Removing the remote origin using

git remote rm origin

setting the http url using

git remote add origin https://github.com/<<Entire Path of the new Repo>>

git push origin master

Above steps successfully added code to repo.

回答6:

I fixed it by readding the key to my ssh-agent. For some reasons it was gone.

回答7:

You probably have to add your public key to github. https://help.github.com/articles/generating-ssh-keys

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

This worked for me. Simplest solution by far.

If you are using GitHub for Windows and getting this error, the problem might be that you are trying to run the command in the wrong shell or mode. If you are trying to do git push origin master in the regular command prompt or PowerShell, this is the problem.

You need to do it in a git shell. Simply open Github for Windows, right click, and select "Open Shell Here". It looks like a regular PowerShell window, but it's not, which makes it really confusing for newbies to git, like myself.

I hope others find this useful.

If you already have your public key added to the GITHUB server there are other solutions that you can try.

In my case the GIT PUSH was failing from inside RUBYMINE but doing it from the Terminal window solved the problem.

In order to deploy to your friend's repo you need to add your public key to the repository's deploy keys.

Go to the repository, go to deploy keys, and add the id_rsa.pub (or whatever yours is named) to "deploy keys".

I believe adding the key to your own account only lets you write to repositories that your account created. If it was created by an organization you need to add the key to the repo's deploy keys.

I faced the same problem.Ask your friend to add you as a collaborator by going to his repo settings and adding a new collaborator.

You will recieve an invite email ,accept it.Then you are good to go. Just make sure that you have added right remote.

This error happened while using Ubuntu Bash on Windows.

I switched to standard windows cmd prompt, and it worked no error.

This is a workaround as it means you probably need to load the ssh private key in ubuntu environment if you want to use ubuntu.
