我的 samba 已停止在 Ubuntu 21.10 上運行，頑皮的，不確定它何時開始，但我在啟動時得到了這個：
$ sudo service smbd restart
[sudo] password for username:
Job for smbd.service failed because the control process exited with error code.
See "systemctl status smbd.service" and "journalctl -xeu smbd.service" for details.
當我運行命令時，它告訴我：
$ systemctl status smbd.service

怎麼了？它抱怨缺少訪客帳戶，但我不想或不使用訪客帳戶？
答案1
解決了我創建了一個無法登入的用戶並將其設定為來賓用戶，現在我意識到我可以將其設定為用戶沒有人似乎具有相同的屬性然後 smbd 開始正常
答案2
Samba 在 Impish 中也不適用於我，錯誤訊息略有不同。顯然與unmasked有關samba-ad-dc.service。這項服務過去一直被掩蓋，因為我相當確定它與 Samba 的客戶端或僅文件伺服器版本（幾乎每個人都使用的版本）衝突。

按照您的建議創建一個用戶nobody（我認為對於這個特定的解決方案來說沒有必要，但似乎是一個好主意）：
$ sudo smbpasswd -a nobody
New SMB password: [enter on blank line]
Retype new SMB password: [enter on blank line]
Added user nobody.
屏蔽samba-ad-dc.service單位：
systemctl mask samba-ad-dc.service
Created symlink /etc/systemd/system/samba-ad-dc.service → /dev/null.
