system-config-samba 崩潰，無法打開配置文件“/etc/libuser.conf”

作業系統：Linux Mint 18.3 Xfce 64 位。

我正在嘗試重新安裝samba，到目前為止我已經完成了：

sudo apt-get install samba cifs-utils system-config-samba

但是在執行配置 GUI 時：

sudo system-config-samba

它像這樣崩潰：

Traceback (most recent call last):
 File "/usr/sbin/system-config-samba", line 45, in <module>
   mainWindow.MainWindow(debug_flag)
 File "/usr/share/system-config-samba/mainWindow.py", line 121, in __init__
   self.basic_preferences_win = basicPreferencesWin.BasicPreferencesWin(self, self.xml, self.samba_data, self.samba_backend, self.main_window)
 File "/usr/share/system-config-samba/basicPreferencesWin.py", line 97, in __init__
   self.admin = libuser.admin()
SystemError: could not open configuration file `/etc/libuser.conf': No such file or directory

足以創建該文件：

sudo touch /etc/libuser.conf

並重新執行 samba 配置器。
