I have one Python file, main.py. I would like to be able to make a .deb package from it, and then be able to run main.py by typing the package name from the terminal. It is written in Python 3, so the package name should run:

python3 main.py

The only dependency I know of is python3.

I have tried creating a deb with a dependency of python3, and then running python3 packagename, but I get:

/usr/bin/python3: can't find '__main__' module in 'packagename'

Trying to use Debreate for package creation fails to open with :

Traceback (most recent call last): File "/usr/bin/debreate", line 12, in <module> import wx, sys, os, debreate, db, language, shutil File "/usr/share/debreate/debreate.py", line 23, in <module> import os, sys, wx.lib.dialogs, db, webbrowser, language, shutil, subprocess File "/usr/share/debreate/db.py", line 5, in <module> import wx, wx.combo, wx.lib.mixins.listctrl as LC, os, sys, language ImportError: No module named combo

    I have left a comment below the post of @andrewsomething to update it for Python 3. In the meantime please edit your question to include what you have already tried and what are the results/error that you get. Commented Jan 3, 2014 at 16:15

    have you tried fpm? FUNDAMENTAL PRINCIPLE: IF FPM IS NOT HELPING YOU MAKE PACKAGES EASILY, THEN THERE IS A BUG IN FPM. Commented Mar 10, 2014 at 9:10

Creating a .deb for a python3 script is very simple, and only requires a few changes in debian/rules and debian/control if you're familiar with python2 packaging.

In a nutshell:

  1. Create the package source dir

    mkdir myscript-0.1

  2. Copy your python3 script (or the sample script below) to the source dir

    cp ~/myscript myscript-0.1 cd myscript-0.1

    Sample script:

    #!/usr/bin/python3 if __name__ == '__main__': print("Hello world")

  3. Create the packaging skeleton (debian/*)

    dh_make -s --indep --createorig

  4. Remove the example files

    rm debian/*.ex debian/*.EX debian/README.*

  5. Edit debian/control

    Replace its content with the following text:

    Source: myscript Section: utils Priority: optional Maintainer: Name, Build-Depends: debhelper (>= 9), python3 Standards-Version: 3.9.5 X-Python3-Version: >= 3.2 Package: myscript Architecture: all Depends: ${misc:Depends}, ${python3:Depends} Description: insert up to 60 chars description insert long description, indented with spaces

  6. debian/install must contain the script to install as well as the target directory

    echo myscript usr/bin > debian/install

  7. Edit debian/rules

    Replace its content with the following text:

    #!/usr/bin/make -f %: dh $@ --with=python3

    Note: it's a TAB before dh $@, not four spaces!

  8. Build the package

    debuild -us -uc

You will get a few Lintian warnings/errors but your package is ready to be used:

../myscript_0.1-1_all.deb

  • Do you know how to include translations (PO/POT) into the DEB file? I think there's a command needed within debian/rules but I've never been able to figure it out. Commented Aug 16, 2014 at 0:21

    @Bernmeister, Please create a new question about translation support. I'd prefer to keep this one as simple as possible. Thanks Commented Aug 26, 2014 at 7:41

For the error you encounter in debreate,

sudo apt-get install python-wxgtk2.8
