Unable to Git-push master to Github - 'origin' does not appear to be a git repository / permission denied

Question

This question is related to my problem in understanding rebase, branch and merge, and to the problem

How can you commit to your github account as you

Answer 1

VonC's answer is best, but the part that worked for me was super simple and is kind of buried among a lot of other possible answers. If you are like me, you ran into this issue while running a "getting started with rails" tutorial and you had NOT setup your public/private SSH keys.

If so, try this:

1. $>cd ~/.ssh

2. $>ls

3. If the output of ls is known_hosts and nothing else, visit: http://help.github.com/mac-key-setup/ and start following the instructions from the "Generating a key" section and down.

After running those instructions, my "git push origin master" command worked.

Answer 2

One possibility that the above answers don't address is that you may not have an ssh access from your shell. That is, you may be in a network (some college networks do this) where ssh service is blocked.In that case you will not only be able to get github services but also any other ssh services. You can test if this is the problem by trying to use any other ssh service.This was the case with me.

Answer 3

What does

$ git config --get-regexp '^(remote|branch)\.'

returns (executed within your git repository) ?

Origin is just a default naming convention for referring to a remote Git repository.

If it does not refer to GitHub (but rather a path to your teammate repository, path which may no longer be valid or available), just add another origin, like in this Bloggitation entry

$ git remote add origin2 git@github.com:myLogin/myProject.git
$ git push origin2 master

(I would actually use the name 'github' rather than 'origin' or 'origin2')

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

Check if your gitHub identity is correctly declared in your local Git repository, as mentioned in the GitHub Help guide. (both user.name and github.name -- and github.token)

Then, stonean blog suggests (as does Marcio Garcia):

$ cd ~/.ssh
$ ssh-add id_rsa

Aral Balkan adds: create a config file

The solution was to create a config file under ~/.ssh/ as outlined at the bottom of the OS X section of this page.

Here's the file I added, as per the instructions on the page, and my pushes started working again:

Host github.com
User git
Port 22
Hostname github.com
IdentityFile ~/.ssh/id_rsa
TCPKeepAlive yes
IdentitiesOnly yes

You can also post the result of

ssh -v git@github.com

to have more information as to why GitHub ssh connection rejects you.

Check also you did enter correctly your public key (it needs to end with '==').
Do not paste your private key, but your public one. A public key would look something like:

ssh-rsa AAAAB3<big string here>== tek...@gmail.com 

(Note: did you use a passphrase for your ssh keys ? It would be easier without a passphrase)

Check also the url used when pushing (git@github.com/..., not git://github.com/...)

Check that you do have a SSH Agent to use and cache your key.

Try this:

 $ ssh -i path/to/public/key git@github.com

If that works, then it means your key is not being sent to GitHub by your ssh client.
