mrbayes-mpi is:

Bayesian inference of phylogeny is based upon a quantity called the posterior probability distribution of trees, which is the probability of a tree conditioned on the observations. The conditioning is accomplished using Bayes’s theorem. The posterior probability distribution of trees is impossible to calculate analytically; instead, MrBayes uses a simulation technique called Markov chain Monte Carlo (or MCMC) to approximate the posterior probabilities of trees.

This package offers a binary compiled for parallel computation with MPI.

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

sudo apt-get -y install mrbayes-mpi

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

You can also use apt command to install mrbayes-mpi.

sudo apt -y install mrbayes-mpi
