Ubuntu Server 20.04 在 Raspberry Pi 4 上全新安装并安装cifs-utils。
sudo mount.cifs //192.168.0.5/SharedDirectory /home/ubuntu/windowshare -o user=myusername,password=mypass
上述用于挂载 Windows 共享目录的命令在 Raspberry OS 上完美运行。
尝试对安装在 Raspberry Pi 4 上的 Ubuntu Server 20.04 执行相同操作，无论我们做什么更改，它总是会抛出以下错误
mount error(2): No such file or directory
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

阅读了一些帖子和文章后尝试了以下选项，但没有成功：
- 禁用 ipv6
- vers=1.0（也尝试过 2.0、3.0）
- noauto，x-systemd.automount
编辑：还尝试启用以下服务
sudo systemctl enable systemd-networkd-wait-online
sudo systemctl enable systemd-networkd.service
sudo systemctl enable NetworkManager-wait-online.service

解决。
Windows 防火墙防御者正在阻止它。
必须在防火墙设置中的允许应用中允许@netlogon.dll。
