Issues installing v2312 on Debian 12 (bookworm)

Hi, I'm trying to install v2312 in the latest continuumio/miniconda3 docker image, which is based on Debian 12 (bookworm): openfoam-gmsh.dockerfile.

I am getting the classic error, E: Unable to locate package openfoam2312-default, despite bookworm being present in the repo. Not sure what could be causing this. I would love to start from the miniconda docker image, so any advice would be appreciated.
