Hello Jacobs.smith,

Not sure about your complete code/requirement(as you haven't shown us) but seems like it may be code is executing a process into a sub-shell then there it is expecting a variable to be passed rather than it gets passed while running the script.

Thanks,

DH_PYTHON(1)							     Debhelper							      DH_PYTHON(1)

NAME
dh_python - calculates Python dependencies and adds postinst and prerm Python scripts (deprecated) SYNOPSIS
dh_python [debhelperoptions] [-n] [-V version] [moduledirs...] DESCRIPTION
Note: This program is deprecated. You should use dh_python2 instead. This program will do nothing if debian/pycompat or a Python-Version control file field exists. dh_python is a debhelper program that is responsible for generating the ${python:Depends} substitutions and adding them to substvars files. It will also add a postinst and a prerm script if required. The program will look at Python scripts and modules in your package, and will use this information to generate a dependency on python, with the current major version, or on pythonX.Y if your scripts or modules need a specific python version. The dependency will be substituted into your package's control file wherever you place the token ${python:Depends}. If some modules need to be byte-compiled at install time, appropriate postinst and prerm scripts will be generated. If already byte- compiled modules are found, they are removed. If you use this program, your package should build-depend on python. OPTIONS
module dirs If your package installs Python modules in non-standard directories, you can make dh_python check those directories by passing their names on the command line. By default, it will check /usr/lib/site-python, /usr/lib/$PACKAGE, /usr/share/$PACKAGE, /usr/lib/games/$PACKAGE, /usr/share/games/$PACKAGE and /usr/lib/python?.?/site-packages. Note: only /usr/lib/site-python, /usr/lib/python?.?/site-packages and the extra names on the command line are searched for binary (.so) modules. -V version If the .py files your package ships are meant to be used by a specific pythonX.Y version, you can use this option to specify the desired version, such as 2.3. Do not use if you ship modules in /usr/lib/site-python. -n, --noscripts Do not modify postinst/prerm scripts. CONFORMS TO
