Create a debian package to install python scripts to /usr/local/bin in Ubuntu

Question

I try to create a debian package of a python application as follows:

Write a setup.py
Generate a debian folder by stddeb
Run dpkg-buildpackage -b -rfakeroot -uc to build the debian package

The setup.py is like

#!/usr/bin/env python

from distutils.core import setup

setup(name='foo',
      version='1.0.0',
      description='Foo example',
      author='Kuan-Kai Chiu',
      author_email='[email protected]',
      scripts=['src/foo.py']
     )

How do I install the foo.py to /usr/local/bin instead of being installed to /usr/bin? I know there's an option --install-scripts=/usr/local/bin while running python setup.py install, but I have to debianize my python application and it seems no way to specify the install-scripts prefix.

Thanks in advance!

If you just want to install a file in /usr/local/bin/, then drop the setup.py as it's not really needed. If you are using dh in your package (you can see if you are by checking it's being invoked in your debian/rules file. If you aren't using it, you should :-), then you'll only have to feed dh_install (see its manpage) with an install file. The syntax of this file is really simple, you have to specify what do you want to install, and where. You can do this by issuing the following command in the root directory of your package:

$ echo "src/foo.py usr/local/bin" > debian/install

Now, as you want to install a script under /usr/local/, and this is against the Debian policy, one of the dh_* tools will fail. This tool is dh_usrlocal. The fix is quite simple. We just have to tell debian/rules that we don't want to run it, and we can do this by overriding its behavior. This is how your final debian/rules should look:

#!/usr/bin/make -f
# -*- makefile -*-

%:
    dh $@ 

override_dh_usrlocal:

That's it. Run dpkg-buildpackage and you should have your fresh new packages in ../.

Man I wish I could up-vote much more than +1. override_dh_usrlocal: is what I've been searching the past 40min to find! Except I was looking for an env var to set or similar in rules instead. Anyway, thanks for that which appears to be the only mention of it on the internet!
