我的 samba 已在 Ubuntu 21.10 上停止工作，不确定它什么时候启动，但我在启动时得到了这个：
$ 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.
当我运行命令时，它说我得到：
$ systemctl status smbd.service

出了什么问题？它抱怨缺少访客帐户，但是我不想要或使用访客帐户？？？
答案1
解决了我创建了一个无法登录的用户，并将其设为来宾用户，现在我意识到我本可以让该用户 nobody 似乎具有相同的属性，然后 smbd 就可以正常启动了
答案2
Samba 在 Impish 中也无法正常工作，错误消息略有不同。显然与 unmasked 有关samba-ad-dc.service。此服务过去一直被屏蔽，因为我相当确定它与 Samba 的客户端或文件服务器版本（几乎每个人都在使用）相冲突。

采纳您的建议来创建一个用户nobody（我认为对于这个特定的解决方案来说这不是必需的，但似乎是个好主意）：
$ sudo smbpasswd -a nobody
New SMB password: [enter on blank line]
Retype new SMB password: [enter on blank line]
Added user nobody.
掩蔽samba-ad-dc.service单元：
systemctl mask samba-ad-dc.service
Created symlink /etc/systemd/system/samba-ad-dc.service → /dev/null.
运行包管理自动修复：
