如何使用我的 github 配置文件 SSH 密钥来修改我的所有存储库？

Question

I've inserted a SSH key in my github profile, and then I tried to push some changes, but I received the error: Permission denied (public key). I tried the solutions of the GitHub Docs, but it didn't work for me, I even tried this:

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

How can I modify my repos with SSH if I have a SSH key set in my GitHub Profile?

Answer 1

As commented, the GitHub documentation does illustrate adding the private SSH key (not its parent folder) to ssh-agent

# start the ssh-agent in the background
$ eval `ssh-agent -s`
> Agent pid 59566
$ ssh-add ~/.ssh/id_ed25519

That being said, you can:

• start with a private key which is not passphrase protected first, for testing

• check if the key is properly detected/used with

   ssh -Tv git@github.com # or, for a custom key filename: ssh -Tv -i /path/to/my/private_key git@github.com

You should see a welcome message ('Hi, ...')
