Fixing missing library in Debian repos

[jsgarcia-cgiar]

When trying to build the backend image I got the following error:

I followed these instructions: https://askubuntu.com/a/1520333. And the image built successfully.

What I basically did was replace an unsupported package that was no longer in the Debian repositories for the image being used for Python in this Dockerfile.
