Packaging python script to Debian follows strict instructions, using the following instructions, most of the steps can be skipped hence making it easy and fast.
If you like video go to https://www.youtube.com/watch?v=a9GzDZB5VeU. This video doesn't show setup.py file creating which is required, but excluding that portion everything is same as below.

mymood debian changelog compat control rules copyright mymood __init__.py mymood.py command_line.py README.md setup.py
Don't create the above structure, it will be created as you go through below steps.
$mkdir mymood $cd mymood $mkdir debian $mkdir mymood
Goto mymood/mymood directory and paste mymood.py script as shown in project structure.
Within mymood/mymood create __init__.py
Within mymood/mymood directory create command_line.py. setup.py needs this to run script from bash just by typing mymood.
$vim command_line.py
copy the following into command_line.py
from mymood import analyze def main(): analyze()
Create a setup.py file in mymood directory as shown in project structure above.
The below code is simple and minimal setup.py for mymood, copy and change as you require.
from setuptools import setup
setup(name='mymood',
version='0.1',
description='your mood analyzer',
author='mp',
author_email='hello@micropyramid.com',
license='MIT',
packages=['mymood'],
entry_points = {
'console_scripts': ['mymood=mymood.command_line:main'],
},
zip_safe=False)
Console scripts is used to run the script from terminal. So from bash you can just type mymood and run the script.
$mkdir debian
Devscripts package is needed to create changelog file.
$cd debian $sudo apt-get install devscripts $dch --create
Now edit the file as follows:
mymood (1.0) UNRELEASED; urgency=medium * Initial release. (Closes: #XXXXXX) -- druuu <druuu@gmail.com> Wed, 10 Feb 2016 15:33:03 +0530
$touch compat $touch copyright $touch control $touch rules
the control file looks like:
Source: mymood
Section: python
Priority: optional
Maintainer: druuu, <druuu@gmail.com>
Build-Depends: debhelper (>= 7),
Standards-Version: 3.9.2
Package: mymood
Architecture: all
Section: python
Depends: python, ${misc:Depends}, ${python:Depends}
Description: simple mood checker
mymood is a simple mood checker.
It analyze the mood by simple questions.
So this file lists dependencies, package description. The description is of two types, short and long.
Short is "simple mood checker' and the long 'mymood is a simple mood checker. It analyze the mood by simple questions'.
In the long description it should not exceed 80characters per line.
#!/usr/bin/make -f %: dh $@ --with python2
Note that you have python2 or python3 based on your script, dont just put python.
Also not that you use tab before dh, not spaces
The other files can be left empty.
Goto mymood top level direcotry and build package.
mymood <-- you should be inside this directory debian changelog compat control rules copyright mymood __init__.py mymood.py command_line.py README.md setup.py
$fakeroot dpkg-buildpackage -b
This should create the following structure:
mymood_1.0_all.deb <--success! we got deb package mymood_1.0_amd64.changes mymood build debian tmp DEBIAN etc.. usr etc.. changelog compat control rules copyright debhelper.log files substvars mymood __init__.py mymood.py command_line.py mymood.egg-info README.md setup.py
As you can see we get mymood_1.0_all.deb package wich can be installed by "ubuntu software center".
Ubuntu Software Center is recomended as it automatically installs dependencies
or
simply
$sudo dpkg -i mymood_1.0_all.deb <-- this command throws errors if dependencies not satisfied. Use ubuntu softare center.
