How to update dockerfile to update version of popper-utils' pdftotext?

Question

I currently have a project I'm working on where the version of pdftotext from poppler-utils is using the "testing" version (found here https://manpages.debian.org/testing/poppler-utils/pdftotext.1.en.html). Instead, I want to use the version "experimental" by updating the debian image in the dockerfile (trying to avoid conflicts with other items). Is there a simple way to do this or is this not feasible?

Answer 1

As usual, I figured out the solution. I got some data from this post that provided some good insight on the commands. I had to update to the version that would work with my bot base but got it all figured out. Installing Poppler utils of version 0.82 in docker
