Unable to start "gksu system-config-samba"

[Richard Elkins]

I installed the samba server packages plus system-config-samba. Next, I attempted to run the Samba configuration applet from the "System" section of the "Settings" menu item. The results is as follows:

Error
Unable to start "gksu system-config-samba"
Failed to execute child process “gksu” (No such file or directory)

When I run `sudo system-config-samba` in a terminal window, I see this:

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

Next I tried `sudo touch /etc/libuser.conf` since I know that this was a work-around for the same symptoms in the past (Ubuntu 15.04, Bug #1453223). Now, I can successfully run `sudo system-config-samba` in a terminal window. However, the applet still fails with the same symptoms.

Please note that I am not stuck; my Samba server is working fine. My maintenance work-around is to edit /etc/samba/smb.conf by hand and then restart the smbd service manually - an oldie that still suffices.

Feel free to contact me if the automatically-attached evidence is not sufficient for investigation.

Yes, this was a fresh install of 17.10 Beta 2 followed by an apt upgrade of packages.

Some system logs which might help are are inside the tar.gz file.

Thanks for reporting. It's already known - see bug 1713311.
Please mark as duplicate (I got timeout issue).

[Richard Elkins (texadactyl)]

Symptoms gone in 17.10.

[Norbert (nrbrtx)]

Bug is still actual for 17.10 with GNOME on Wayland.

This error is also present in Ubuntu 18.04.LTS on aarch64 for Rockchip.
