How To Fix genx: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu genx is provided by python3-genx package.

python3-genx is:

GenX is a versatile program using the differential evolution algorithm for fitting, primarily, X-ray and neutron reflectivity data, lately also surface x-ray diffraction data. The differential evolution algorithm is a robust optimization method which avoids local minima but at same is a highly effective. GenX is written in Python and uses the wxpython package for the Graphical User Interface (GUI). A model to fit is defined either through a GUI plug-in or via a Python script. The possibility to script everything makes it easy to develop completely new fitting model. Clearly, GenX is extremely modular, making it possible to extend the program with models and plug-ins for most fitting problems. At the present GenX is shipped with models for x-ray and neutron specular reflectivity, off-specular x-ray reflectivity and surface x-ray diffraction

To fix this problem, we can install more using the command below.

sudo apt-get -y install python3-genx

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install python3-genx.

sudo apt -y install python3-genx

Or if you have aptitude installed you can use the following command.

sudo aptitude install python3-genx
