Unable to push code on github?

Question

I have successfully pushed one app code onto github. I had set up the ssh key and added it to github.

But then I started working on another app and tried to push it onto github using:

git remote add github git@github.com:user_name/demo_app.git
git push -u github master

Then I got the following error:

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

I have also tried changing the name of the remote Git repository but that didn't work too.

I tried $ssh -v git@github.com to get more information and this is what i got.

-bash: cd: ../.ssh: No such file or directory
abhimanyu@sourcebits-Ubuntu:~/Aptana_Studio_3_Workspace/demo_app$ cd ~/.ssh

While i was setting the ssh key I was asked for a passphrase and I didnt leave it blank.

Any suggestion would be appreciated.

"another app"? do you have forket this other app and do you have its repo listed as one of your repos on your GitHub account page? — VonC, Jun 14 '11 at 15:13
@Ivan - I wrote that line by mistake...I actually used this: git remote add github git@github.com:user_name/demo_app.git — Abhimanyu, Jun 14 '11 at 15:52

There are a few reasons why you can get this issue:

Typo: Having a typo anywhere while adding remote can cause the problem.
Wrong SSH key: This can happen if your ssh key changed and you are accessing the repo again.
Access Revoke: If your access to the project is revoked, you can get this error.
Incorrect SSH key - Make sure that \n is not copy-pasted from the ssh key.

You can try to replace it manually on the git config:

$ vi (or any other text editor) .git/config

Replace the url by: url = git@github.com:username/reponame.git

If you do not own the repository, make sure that you are a contributor. Have the admin add you under settings.

I had this problem with bitbucket,

Might help others to know: I found the solution that worked best for me was breaking up the push into smaller chunks. Removing the large screenshot image files (10mb+) from the commits

Security was not the issue in the end more about limits of bin files

It looks like you are trying to push to a repository that you do not own. To push to another user's repository, you need to fork it on the GitHub website. This will give your account access to a branch on that repository.

Make sure to create a matching branch on your local repository and then push from that branch. In order to push to the 'master' branch, you either need to be added as a collaborator or make a pull request so that the owner can merge your work to the master branch.

I think the problem is here:

git remote add github github@github.com:user_name/demo_app.git

This should be

git remote add github git@github.com:USERNAME/REPONAME.git

That is github@github.com:... should be git@github.com:...
Try this:

# change the remote's url
git remote set-url github git@github:user_name/demo_app.git
# and then try pushing again
git push github master

Reasons a) Write access may not be there to your repo

The best way to figure out try to edit the file, GitHub will tell you , you must have write access

I once has the same problem with

 git remote add github git@github.com:user_name/demo_app.git
 git push -u github master

Then I change the remote URL to use https like this

 git remote add github https://user_name@github.com/user_name/demo_app.git
 git push -u github master

And it works correctly.
