This was done on a clean git clone on the main branch, on arch.
This is most likely due to the main website `deb.debian.org` not hosting buster and related files anymore.
My best guess on fixes is to change the url to a mirror that has the files or update the pod to use a new version of debian

Empieza inspeccionando la definición de compilación del contenedor utilizada por `podman build -t lontronix/devcade .`, especialmente la imagen base `python:3.8-buster` y el paso de instalación de `requirements.txt`. Vuelve a ejecutar la compilación para confirmar el fallo del repositorio de Debian y, después, verifica que la compilación actualizada se complete correctamente en un clon limpio.
