[mythtvnz] New install - mythbackend password not accepted

Ok ,I tried your scripts which don't appear to work correctly in this system

While running htop in another workspace ,I can issue sudo 
/home/mythtv/bin/mythtv-systemctl-helper.sh stop and sudo 
/home/mythtv/bin/mythtv-systemctl-helper.sh start commands and observe 
that the processes related to /usr/bin/mythtv disappear and reappear.

If I start mythtv backend setup ,first I get a window asking to stop 
myth backend ,I click yes, I get another window asking for the password 
and I close it.

Myth backend setup starts and says myth backend is still running ,htop 
confirms this, there are 3 choices: 'stop backend' , 'continue' or 'exit'.

'Continue' allows me to  make changes  using the setup app. 'Stop 
backend' freezes the workspace. I can switch workspaces to where htop is 
running and see there are /usr/bin/mythtv processes running - workspace 
2 is not frozen. I can issue sudo 
/home/mythtv/bin/mythtv-systemctl-helper.sh stop in the terminal and the 
mythtv processes stop. Back in workpace 1  the frozen myth backend setup 
gui closes and leaves a mythtv terminal which along with other messages 
says "trying to close mythbackend" and "connection to mythbackend was lost"

This freezing of the workspace happened before running your scripts. The 
scripts have allowed the closure of the password request box without it 
respawning.Before the scripts I had to click ok 3 times and then the 
password box would not come back.

It might be easier for you to point me to an up to date install 
procedure for OSs that use systemd  and for me to do a reinstall.

During the mythtv install via myth control panel ,the installer exited  
due to the absence of 'pwgen' which appear to be an old bug: 
https://bugs.launchpad.net/ubuntu/+source/mythtv/+bug/592521 
<https://bugs.launchpad.net/ubuntu/+source/mythtv/+bug/592521> but I 
never encountered it when Mythbuntu was available.

I have a very strong suspicion there were setup option request windows 
hidden by the "failed to install message" box ,there was a box with a 
"default" button revealed when the closed "failed to install message" box

I installed pwgen and started myth control panel which seemed to be 
happy except for asking for passwords.

What is the best way to remove all trace of mythtv including config 
files from the system  and begin again?

Do you think Myth Control Panel complicates the install?

Thanks for you help
