Installation problem on local ubuntu server

Hi All,

I did install some ERP NEXT on AMAZON server and it is working.
I tried installed ubuntu on the local ubuntu 16.04 server and it failed with same command.

after that, i run the command below:

sudo apt-get update
sudo apt-get install python-minimal
sudo apt-get install build-essential python-setuptools
sudo adduser frappe
sudo usermod -aG sudo frappe
su - frappe

wget https://raw.githubusercontent.com/frappe/bench/master/playbooks/install.py
sudo python install.py --production

However. i’m getting the error below.
May i know what is the cause and how to fix this?
Appreciate your help.

No package matching ‘dnsmasq’ is available

when i try to apt-get install

i get the error below

It’s working perfectly fine when I tested it.
Can you post the output of cat /etc/apt/sources.list
