Ubuntu 16.04 LTS : thermald - failures

I have down downloaded and installed the bug fix provided in https://launchpad.net/ubuntu/+source/thermald/1.5-2ubuntu1.

Executed the following commands as described in README.txt:

Building on Ubuntu
1. Install
 sudo apt-get install autoconf
 sudo apt-get install g++
 sudo apt-get install libglib2.0-dev
 sudo apt-get install libdbus-1-dev
 sudo apt-get install libdbus-glib-1-dev
 sudo apt-get install libxml2-dev
2
Build
 ./autogen.sh
  ./configure prefix=/usr
 make
 sudo make install
(It will give error for systemd configuration, but ignore)
cp data/thermald.conf /etc/init/
3.
Use "sudo start thermald" to start
Use "sudo stop thermald" to stop

However, I could not start thermald on command line. See below
$ sudo cp data/thermald.conf /etc/init/
$ sudo start thermald
start: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused

Appreciate further instructions to resolve this failure.

After rebooting, the same thermald failures in the systemlog appears. Neither can it be started on command line.

A new thermald update (found in Ubuntu Software Updates) was installed this morning.
After rebooting the system, new thermald failures report in system logs are:

I have checked /dev directory. The file /dev/acpi_thermal_rel does not exist after executing ls -la.
