/etc/ssh/sshd_config看起來像這樣：Pastebin.ubuntu.com 鏈接。這是預設的，除了我取消註解授權金鑰、pubkey auth 和listenaddress。
然後我做了ssh-copy-id -i ~/.ssh/id_ed25519 user@host，之後我可以看到該authorized_keys文件在那裡並且是正確的。然後我sshd用--full-restart鑰匙重新啟動。之後我在嘗試連線時總是得到以下資訊：

如果我停用密碼身份驗證，我的權限會立即被拒絕。而且我從來沒有被要求輸入密鑰的密碼。
為了測試，我在虛擬機器（Xubuntu）上對 sshd 執行了完全相同的步驟，一切正常。我使用了相同的金鑰，並且可以從 WSL ssh 用戶端進行連線。
