How to fix "set -e -o pipefail" (CentOS script) for Ubuntu 18.04 LTS?

I'm working with a set of scripts that automate some bioinformatics (mitoVGP; https://github.com/VGP/vgp-assembly/tree/master/mitoVGP) and then the install is done as a conda environment.

The problem (sh symlinked to dash, as opposed to bash) has been outlined by @SergiyKolodyazhnyy in the first answer here: "set -e -o pipefail" not working on bash script on Ubuntu 16

So, my question is, how do I fix these scripts, or else make it such that invoking them with makes them such that they work/run in a bash environment on Ubuntu?
