Git push: 权限拒绝(公钥)

我试图把一个文件推到一个朋友的 git 回购，但错误的公开密钥。

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

我们在哪里以及如何定义公钥/私钥？

返回:

origin  git@github.com:Sesamzaad/NET.git (fetch)
origin  git@github.com:Sesamzaad/NET.git (push)

感谢你的帮助。

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

I was facing same problem and 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 git@github.com:<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 -

cat ~/.ssh/id_rsa.pub

If you hadn't specified a different path then this will be the default path.

Add this key to your github account.

Next do -

ssh -T git@github.com

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. Get your public SSH key with 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

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.

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.

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.

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

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 fixed it by re-adding the key to my ssh-agent.

with the following command:

ssh-add ~/.ssh/path_to_private_key_you_generated

For some reasons it was gone.

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.

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.

You need to fork the project to your own user repository.

Then add origin:

git remote add upstream your-ssh-here
git fetch upstream
git branch --set-upstream-to=upstream/master master

The documentation from Github is really explanatory.

https://help.github.com/en/articles/adding-a-new-ssh-key-to-your-github-account https://help.github.com/en/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent

I think you must do the lasts steps from the guide to proper configure your keys

$ eval "$(ssh-agent -s)"
$ ssh-add ~/.ssh/id_rsa

  2. Select git-bash here problem
  3. Write command ssh-keygen by this command your key is generated
  4. Copy the key from cmd or go to (C:/User/your_user/.ssh/)
  5. open id.rsa with notepad.
  6. Copy your key
  7. Now go to your git-hub profile
  8. Go to settings
  9. select SSH and Gpg keys
  10. select New ssh key option
  11. add window-key in the title
  12. Paste your key in the description part below title field

Now you are ready to push your folder

  1. Now go to folder you want to upload
  2. right click on the folder
  3. Select git bash here
  4. git init

  6. git commit -m "first commit"
  7. git remote add origin https://github.com//

If you have your private key(s) in ~/.ssh and have added them to https://github.com/settings/ssh, but still are unable to commit to a Github repo added via ssh, make sure they are added to your ssh-agent:

ssh-add -k ~/.ssh/[PRIVATE_KEY]

You can add multiple private keys for multiple servers (e.g. Bitbucket & GitHub) and it will use the correct one when dealing with git.

If you are getting 403 error here is the solution:

 The requested URL returned error: 403

As you are having your account registered with another account so you need to remove the github credentials from windows

control panel > user accounts > credential manager > Windows credentials > Generic credentials


then remove the Github keys

If ssh key is already generated in your git account, then just do the following-

ssh-add -k ~/.ssh/id_rsa

May be, if another answers don't help try to run git remote -v

If you see:

origin  https://github.com/<name/repo.git> (fetch)
origin  https://github.com/<name/repo.git> (push)

(origin starts with https or http)

Run git remote set-url origin git@github.com:<name/repo.git>

and than git push again

I can ssh the connect git@github.com, and return the successful window, but cannot push anything to github, the server return that:

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

how I solve the question:

delete the origin and re-add it:

git remote rm origin

git remote add origin git@github.com:<xxxx>/<xxxx>.git

git branch -M main
git push -u origin main

the terminal returns:

Counting objects: 100% (3/3), done.

Compressing objects: 100% (2/2), done.

To make things clear, there are two ways to connect to your git repository from your PC:

  1. Using SSH which has the following format : git@github.com:username/repository-name.git

  2. Using HTTPS which has the following format: https://github.com/username/repository-name.git

You have the absolute right to choose whichever is best for you.

If you choose to go for (1) then you have to establish the SSH connection between your PC and git account (find the steps from the answers above to know how to do it).

Alternatively, you can choose (2) and connect via HTTPS which does not require you to establish SSH on your PC, so you won't get the permission denied (public key) issue as long as your git account is already verified on the PC and connected.

For windows 10

  1. In the command prompt, type the following: ssh-keygen

  2. By default, the system will save the keys to C:\Users\your_username/.ssh/id_rsa. You can use the default name, or you can choose more descriptive names. This can help distinguish between keys, if you are using multiple key pairs. To stick to the default option, press Enter.

Note: If a file with the same name already exists, you will be asked whether you want to overwrite the file.

  1. You’ll be asked to enter a passphrase. Hit Enter to skip this step.

  2. The system will generate the key pair, and display the key fingerprint and a randomart image.

  3. Open your file browser.

  4. Navigate to C:\Users\your_username/.ssh.

  5. You should see two files. The identification is saved in the id_rsa file and the public key is labeled id_rsa.pub. This is your SSH key pair.

  6. Copy the key, including the "ssh-rsa" but excluding your computer name at the end

  7. Go to https://github.com/settings/ssh Add your SSH key

  8. Go to repo folder and add your user name by using this command, type the following: git remote add origin git@github.com:git_hub_user_name/your_repo_name.git

  9. ssh -T git@github.com

Now you should see success message.

Set global variable

export GIT_SSH_COMMAND="ssh -v"

Now you see which keys are used. E.g. with

git remote show origin

If you have the same problem as i do, you see

debug1: send_pubkey_test: no mutual signature algorithm

This can be solved with

PubkeyAcceptedKeyTypes +ssh-rsa

in your

~/.ssh/config

or by generating a better key.
