In Ubuntu gyoto-mpi-worker.8 is provided by gyoto-bin package.

gyoto-bin is:

Gyoto is a framework for computing geodesics in curved space-times. The gyoto utility program uses this framework to compute images of astronomical objects in the vicinity of compact objects (e.g. black-holes). Such images are distorted by strong gravitational lensing. The gyoto program takes a scenery description in XML format, computes this scenery using relativistic ray-tracing, and saves the result in FITS format.

This package contains the `gyoto’ command-line utility. More complex uses of the Gyoto framework can be achieved using the python3-gyoto or yorick-gyoto packages. Gyoto can be extended with plug-ins (see libgyoto8-dev).

MPI parallelization requires the mpi-default-bin package. Producing videos requires the python3-gyoto and python3-opencv packages.

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

sudo apt-get -y install gyoto-bin

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

You can also use apt command to install gyoto-bin.
