I installed your helper scripts and it is looking good but with a couple 
of idiosyncrasies.

I was running htop on a second workspace to monitor the stopping and 
starting of the backend.

When I start myth backend setup  a small dialogue opens stating that 
myth backend needs to be closed > selecting 'Yes' results in a mythtv 
dialogue asking for a password - which won't accept the sudo password or 
any password in the known universe. NB there are two users: the Xubuntu 
user called myth and mythtv , I don't know if that is enlightening.

The password dialogue is despatched into the land of wind and ghosts 
with a simple esc keystroke or clicking 'X' or "Cancel"

A terminal window shows myth backend setup starting.

Myth backend setup opens and states the backend is running and htop 
confirms this > selecting 'stop backend' closes the message box and 
,after 10 seconds,myth backend setup is ready for use.

Exiting myth backend setup results in the GUI closing , A terminal 
window shows myth backend  starting, a mythtv dialogue asking for a 
password appears which is  closed with an "esc" . A dialogue opens 
asking if I want to run mythfilldatabase.

htop confirms myth backend is running.

When the helper script commands had the error (typo) the 10 second delay 
was where the Myth backend setup would hang indefinitely.

Except for the irrelevant password requests it seems to be behaving 
pretty much the same as my existing Mythbuntu 16.04 installation.

Set up will continue over following days.
