无法使用 ssh 协议连接 github 存储库

Question

I'm trying to connect to remote github repository using ssh protocol.
After
git remote add origin ssh://username@github.com/foo/project.git
git remote show origin
yields:

Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

ssh -vT git@github.com log:

The https connection to the same project works just fine but I have to log in every time I address the remote repository (by the way, can I outflank it somehow?).
Ssh keys exist and the user have access to them. Could anyone tell what's the problem please?

Answer 1

It seems you didn't add your SSH key to your GitHub account. See this Doc how to do that.

Answer 2

Assuming that you have added the correct public keys to your GitHub account and that you have the proper rights on the remote repository, my guess is that the issue is related to your private key.

You should ensure that either your private key is named id_rsa or that you have the ssh-agent running and the key was added it. If you want to run the ssh-agent and add the keys, try the following:

$ eval `ssh-agent`
$ ssh-add /path/to/private_key

Answer 3

git remote add origin ssh://username@github.com/foo/project.git

这不应该使用username而是git ，如：

git remote add origin ssh://git@github.com/foo/project.git
