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

In Ubuntu mrgscr is provided by abinit package.

abinit is:

ABINIT is a package whose main program allows one to find the total energy, charge density and electronic structure of systems made of electrons and nuclei (molecules and periodic solids) within Density Functional Theory (DFT), using pseudopotentials and a planewave basis.

ABINIT also includes options to optimize the geometry according to the DFT forces and stresses, or to perform molecular dynamics simulations using these forces, or to generate dynamical matrices, Born effective charges, and dielectric tensors. Excited states can be computed within the Time-Dependent Density Functional Theory (for molecules), or within Many-Body Perturbation Theory (the GW approximation). In addition to the main ABINIT code, different utility programs are provided.

This package contains the executables needed to perform calculations (however, pseudopotentials are not supplied). For a set of pseudopotentials, install the abinit-data package.

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

sudo apt-get -y install abinit

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

You can also use apt command to install abinit.

sudo apt -y install abinit

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

sudo aptitude install abinit
