Samba GUI will not start 18.04

Solution 1:

I had the same exact issue. To fix it I ran:

sudo system-config-samba

The very last line of the output read:

SystemError: could not open configuration file '/etc/libuser.conf': No such file or directory

I simply created the file by using:

sudo touch /etc/libuser.conf

and it worked fine.

I couldn't seem to get it to appear in the application screen, but can be run by

sudo system-config-samba

from the terminal.
