今天想抓 git submodule 時，突然出現 Permission denied 錯誤：

$ git submodule update

Cloning into '/artifactory'...
[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
fatal: clone of '[email protected]:platform/release.git' into submodule path '/artifactory' failed
Failed to clone 'artifactory'. Retry scheduled

 

用 ssh 指令測試一下，一樣的 Permission denied 錯誤：

$ ssh -T [email protected]

[email protected]: Permission denied (publickey).

 

到 https://github.xxx.com/settings/keys 看一下，

這才發現 SSH key 已經因為過期，被自動移除了～

(好像沒有收到什麼通知…)

 

趕緊重新產生一組新的 SSH key：

ssh-keygen -t ed25519 -C [email protected]

 

再把產生出的 id_ed25519.pub 檔案的內容，

加到 GitHub SSH keys 裡面：

 

再測試一次，SSH 已經能通了：

$ ssh -T [email protected]

Hi ephrain! You've successfully authenticated, but GitHub does not provide shell access.

 

自然 git submodule 也能抓下來囉：

$ git submodule update

Cloning into '/artifactory'...
Submodule path 'artifactory': checked out 'e9......'
