%{color:red}Manual debugging step by step%
There is a manual in WIKI with says there is a some needed packages dependency 
https://tvheadend.org/projects/tvheadend/wiki/Building
Following this manual (from wiki) there is no chance to make any package
So here is how to solve this:
(Ubuntu 14.04LTS x86_64 used but possible to be used on newer, even "x86" version) 
There is a lot of packages with need to install 
First packages from wiki
sudo apt install build-essential git pkg-config libssl-dev bzip2 wget libavahi-client-dev zlib1g-dev libavcodec-dev libavutil-dev libavformat-dev libswscale-dev libavresample-dev
so let see is this correct by running
./configure
and result is
{{collapse
/opt/tvheadend# ./configure

ERROR: no gettext binaries found

surprise nothing happens 
so we need package gettext
sudo apt install gettext
again configure command

Again missing essential part

And success, there is a chance to build .DEB, but is it so simple are we miss some?
  checking for cc libiconv ...                      fail
  checking for cc libdvben50221 ...                 fail
  checking for pkg liburiparser  ...                fail (detected <none>)
those maby not 100% needed but lets install it:
----
libiconv
there is some strange with this library in newer version it is build in in in other library
sudo apt install libiconv-hook-dev
/// this will not solve dependency error message, maby error in configure script 
----
libdvben50221
this is DVB-CI support for hardware CAM module on some devices
solved by instaling dvb-apps
sudo apt install dvb-apps
----
liburiparser
sudo apt install liburiparser-dev
Let's see with configure

Some will ask about
  checking for cc nvEncodeAPI.h ...                 fail
this is NVENC (nVidia hardware accelerator for transcoding)
I don't use nVidia can't help, there is a separate topic
So let's continue with bulding of .DEB packages.
Next step is to use Autobuild.sh, with will make all automatically. or not.
{{collapse

dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting
dpkg-buildpackage: warning: (Use -d flag to override.)
}}
Again something missing
sudo apt install debhelper libcurl4-gnutls-dev
Crossing fingers an run againAutobuild.sh
If everything is OK, 
compilation of FFMPEG X264/5 OGG AAC and some other codecs will be compiled before TVHeadend and finally .DEB files.
If there is no critical errors at the end there is show something as this
dpkg-buildpackage: binary only upload (no source included)

/opt/tvheadend/../
this mean that I'm using
/opt/tvheadend/ (source from git)
and files are generated in
../ (upper level) in this case
/opt
installation can be done by command
sudo  dpkg -i tvheadend_4.1-2398~gc38af4c_amd64.deb

%{color:red}How to clone Github repo to local folder%
Usually regular command to clone repo is 
git clone https://github.com/tvheadend/tvheadend.git
 
This will download latest source code (unstable) ready for compilation
but if need stable or other
use command
git clone -b release/4.2 https://github.com/tvheadend/tvheadend.git
command explained 
git clone -b <branch> <remote_repo>
branch list can be seen at https://github.com/tvheadend/tvheadend
