My desktop has less then 1/3rd of time network connectivity  running  Ubuntu 18.04  I'm trying to back up and reinstall 16.04 LTS  because in the ubuntu community nobody wants to help  remove the netplan  blackbox network support  that cannot be configured and replace it with the ifupdown  version
When i installed this laptop from scratch with 18.04  it didn't have any network support at all, so i immediately reinstalle to 16.04 

the reason this is happening is that canonical wants users to have black-box networking
the only thing you can select is  wired or wifi and set the ssid/password for your wifi connection

I cannot move forward  because of the failing network support

if I move to 18.04  i lose network connectivty  then   i lose my livelyhood and my business

I removed
apt-get remove qelectrotech qelectrotech-data qelectrotech-examples qet-tb-generator

and installed the downloaded *.deb files
LIBQT5  is installed
but the package will not install ,  de dependency is in error

I followed these instructions
then I had version 0.5   but i could change the colour of a line

so i changed the pinning from
Package: qelectrotech*
Pin: version 0.60.*
Pin-Priority: 1001

to
Package: qelectrotech*
Pin: version 0.70.*
Pin-Priority: 1001

then
apt-get update
apt-get install qelectrotech qelectrotech-data qelectrotech-examples qet-tb-generator

when I start this is about Qelectro 
Qelectro tech v0.5
compilation gcc 5.3.1 2015207 built with Qt5.5.1 ..

now i cannot even change the colour of a line any more
and there is no dual colour
