问题
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:

Failed building wheel for cryptacular
Running setup.py clean for cryptacular
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
回答1:
I had the same issue running python 3.6.6. With this one liner I was able to install cryptacular from the latest commit.
pipenv install -e hg+https://bitbucket.org/dholth/cryptacular@cb96fb3#egg=cryptacular
You will need to have mercurial installed
apt-get update && apt-get install -y mercurial
More info on this thread
回答2:
We don't know the error exactly, but last weekend there was an security update in the base image. Therefore we pinned our python image to 3.6.4.
