! [remote rejected] master -> master (permission denied)

Question

I clone: https://github.com/vy2014/git_lesson.git

Then I make few changes, try to push to remote server by command git push, but error:

Counting objects: 3, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (2/2), done.

remote: Resolving deltas: 100% (1/1), completed with 1 local objects.
To https://github.com/vy2014/git_lesson.git
 ! [remote rejected] master -> master (permission denied)
error: failed to push some refs to 'https://github.com/vy2014/git_lesson.git'

This is git config at local repository (what returned after command git config --list

How I push files to GitHub server?

(I use Git version 2.10.0 on macOS Sierra 10.12)

Answer 1

I'm using Linux that's why answer with osxkeychain don't help me.

And I got same error after enabling 2FA in github

Solution was next:

1. Generate new SSH key and add it to the ssh-agent
2. Add new SSH key to GitHub account
3. Changing remote for repository from https://github.com/username/your-repository.git to [email protected]:username/your-repository.git

It can be done in next way

git remote set-url origin [email protected]:username/your-repository.git

Answer 2

As a complementary, I'm on Fedora and met same error.
By typing git config --global --edit, below content is listed. By removing them, everything work fine then.

  [credential]
  helper = store

Answer 3

Type command:

git config --global --edit

Add these lines of configuration at the end of file:

[credential]
  helper = osxkeychain
  useHttpPath = true
