我在 Ubuntu 20.04 机器上将一个 USB 驱动器安装到 /media/usbdrive。我可以将文件写入除根共享之外的任何共享。这意味着，我将这些共享设置在smb.conf：
[usb]
path = /media/usbdrive
valid users = @samba
force user = shareuser
writable = yes
read only = no
browseable = yes
[apps]
path = /media/usbdrive/Apps
valid users = @samba
force user = shareuser
writable = yes
read only = no
browseable = yes
[music]
path = /media/usbdrive/Music/MP3
valid users = @samba
force user = shareuser
writable = yes
read only = no
browseable = yes
在 Windows 10 (192.168.0.229) 中，我可以通过提供 的密码来访问共享shareuser。然后我可以将文件写入apps和music共享中的任何目录，但不能- 我收到“访问被拒绝”错误。当通过和共享访问时，可以写入通过usb无法访问的相同目录。usbappsmusic
有什么想法吗？我尝试过让 /media/usbdrive 目录拥有不同的所有者，但似乎没有帮助（但也许我遗漏了一些东西）。
