this weekend our docker image broke because it cannot be build anymore. While looking into the stats, I saw this line:
crypt_blowfish-1.2/crypt.h:17:23: fatal error: gnu-crypt.h: No such file or directory
In more detail:

Our implementation works with the package cryptacular which uses bcrypt. None of the packages were updated last week and I dont know where to start.
As additional information, the error occurs in this block of our Dockerfile
RUN apt-get install -y build-essential libfontconfig && \pip install -q -U pip && \pip install -q -r requirements.txt && \apt-get remove -y --purge build-essential && \apt-get autoremove -y && \apt-get clean -y
where the requirements.txt uses cryptacular==1.4.1
Edit: We are working with the python:3.6-slim image
