1. title How to create a Debian Package

Warning: These instructions are incorrect (this is bad hack, not a correct way to create deb package) - they should be fixed according to Ubuntu packaging guide. If you wanna simple guide how to create Debian/Ubuntu package you could read http://www.debian-administration.org/articles/336 (Second part) or use Easy-deb tool for creating deb packages of python modules. This Python Recipe is currently being written, you can fix all errors in this example; feel free to do so Here is a simple example on creating a Debian Package, but it will not be in agreement with the Debian/Ubuntu Policy. You should read that if you want to publish your program in the Debian/Ubuntu repositories. In this example I will use a game developed for PyWeek 5, Twisted Zombie.

First step

The first thing you should know is the folder structure of the Debian Package before you create it. This folder contains three files that are very important, control, twisted-zombie and twisted-zombie.desktop.

DEBIAN/
    control
usr/
    bin/
        twisted-zombie
    share/
        applications/
            twisted-zombie.desktop
        pixmaps/
            twisted-zombie-icon.png
        twisted-zombie/
            data/
            lib/
            COPYING
            README.txt
            create-upload.py
            pyweek-upload.py
            run_game.py

twisted-zombie is the folder of the application itself, pixmaps contains an icon, application contains a desktop file that indicates some options to GNOME, and bin contains a script to execute this game from a console.

control file

In the control file, we will put a short description, long description, package name, package version, etc. Just like the output of the `apt-cache show package` command. The control file contains:

 Package: twisted-zombie
Version: 1.0
Section: games
Maintainer: Manuel Kaufmann <[email protected]>
Architecture: all
Depends: python, python-pygame
Description: Twisted Zombie game
 Twisted Zombie is a game developed for PyWeek 5
 in seven days by programmers of Santa Fé Argentina. 

If you wish, you can put more information about the package. In this page you can find all what you need for this: Binary package control files

twisted-zombie file

In this file we will put what command should be executed when we type `twisted-zombie` in a console. It's simple, it only contains the `python` command with the path of the main .py file. Make sure that it is executable (chmod a+x run_game.py): python /usr/share/twisted-zombie/run_game.py

twisted-zombie.desktop file

In this file we put some options about our application, to tell GNOME -or other desktop- to put our application in the menu, specifying which icon to use, what command to execute, etc...

[Desktop Entry]
Encoding=UTF-8
Name=Twisted Zombie
Version=1.0
Comment=Game developed for PyWeek 5
GenericName=Twisted Zombie Game
Terminal=false
Icon=twisted-zombie-icon.png
Type=Application
Exec=python /usr/share/twisted-zombie/run_game.py
Categories=Game;

Config your application

If you use external files, you should include the following lines in the .py that uses those files:

import os
os.chdir('/usr/share/twisted-zombie')

Build and install our package

In this step we will build our package. For this, we use the following command in the folder that contain our application: $ dpkg --build twisted-zombie/ twisted-zombie-1.0_all.deb And to finish: $ dpkg -i twisted-zombie-1.0_all.deb Done, we have installed our game in our machine. Now, open a terminal, and type `twisted-zombie` or go to the Application Menu -> Games -> Twisted Zombie Game and play it.
