Git gui 使用有 passphrases 的 ssh key 連到 GitHub

因為 2021/08/13 後，github 不給用 https 加密碼方式連線，

只能用 ssh key 的方式。

但是照著步驟一直失敗

Pushing to ssh://github.com/myname/project.git
myname@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

照著新增 ssh key

https://docs.github.com/en/github/authenticating-to-github/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent

打開 git gui 複製使用的 public key

到這頁面按 New SSH key 加入 public key

https://github.com/settings/keys

一開始打開 project/.git/config

直接把 

url = htts://github.com/myname/project.git

改成

url = ssh://github.com/myname/project.git

都顯示失敗，

使用下列測試連線又顯示可以

#ssh -T -i ~/.ssh/private_key git@github.com

後來到 github 的 project 頁面看 ssh 的連線內容

改成git@github.com開頭就可以正常連線，

有 passphrases 也會在第一次時出現對話框。
