列出 SSH -V

如果你按照上述步驟檢查後，還是無法解決問題，請提供 ssh -v ai@raspberrypi.local 的詳細輸出，我會幫助你進一步排查問題！

從你的 SSH 調試輸出中可以看到，現在已經成功使用公鑰驗證登入到 Raspberry Pi。以下是輸出的關鍵部分和解釋：

關鍵輸出解釋

成功連線和驗證：
plaintext
複製程式碼
debug1: Authentication succeeded (publickey).

Authenticated to raspberrypi.local ([fe80::eb61:6965:df5e:3710%en0]:22).

這表示你已經成功使用公鑰驗證登入 Raspberry Pi，無需再輸入密碼。

公鑰成功被伺服器接受：
plaintext
複製程式碼
debug1: Server accepts key: /Users/adamliao/.ssh/id_rsa RSA SHA256:fXva5SVdrOO6ZtU1tm5eeUHKY9lfi+Pf4IONt8bLpzM

伺服器成功接受了 id_rsa 這個私鑰對應的公鑰。

成功進入交互式會話：
plaintext
複製程式碼
debug1: Entering interactive session.

這表示你已經進入了 SSH 交互式會話，可以開始進行命令行操作。

目前狀態

目前的狀態看起來已經完全正常，成功無密碼登入 Raspberry Pi。
如果之前一直要求輸入密碼，現在無需再輸入密碼即可登入，說明設定已經生效。

如果仍然有問題或疑問

確保每次連線都是無密碼登入：確認未來每次連線都無需輸入密碼，試試再次斷開連線，然後重新連線：
bash
複製程式碼
ssh ai@raspberrypi.local

如果不再要求輸入密碼，則說明設置完全生效。
確認權限設置和 sshd_config 檔案：如果未來出現任何問題，請再次檢查權限和 sshd_config 設置：
- ~/.ssh/authorized_keys 的權限應該為 600。
- ~/.ssh 目錄的權限應該為 700。
- sshd_config 應啟用 PubkeyAuthentication 和 AuthorizedKeysFile 設定。
檢查是否有其他公鑰或私鑰：如果有多個公鑰或私鑰對，可能需要刪除或整理不需要的檔案，以避免干擾。

進一步操作（可選）

設置 ssh 配置檔來簡化命令：你可以在 ~/.ssh/config 檔案中設置簡化的連線配置：
plaintext
複製程式碼
Host raspberrypi

HostName raspberrypi.local

User ai

IdentityFile ~/.ssh/id_rsa

這樣可以直接使用以下命令連接：
bash
複製程式碼
ssh raspberrypi

確認和備份 known_hosts 檔案： known_hosts 檔案會保存已知主機的密鑰，確保檔案中沒有過時或錯誤的條目。你可以備份並清理該檔案：
bash
複製程式碼
mv ~/.ssh/known_hosts ~/.ssh/known_hosts.bak

然後嘗試重新連線，生成新的 known_hosts 條目。
