Problems building a Dockerfile

I have started to experiencing issues with building this Docker image in particular:
https://github.com/nextcloud/docker/blob/master/.examples/dockerfiles/full/apache/Dockerfile

Error:

Reading package lists... Building dependency tree... Reading state information... E: Unable to locate package
libmagickcore-6.q16-6-extra E: Couldn't find any package by glob 'libmagickcore-6.q16-6-extra' E: Couldn't find any

Replacing the libmagickcore depdency with a more recent more (say) libmagickcore-7.q16-10-extra is not alone sufficient to fix the issue.

Start with .examples/dockerfiles/full/apache/Dockerfile and reproduce the apt-get install step that fails on libmagickcore-6.q16-6-extra. Check the package names and available repositories involved in that step, then verify that the full Apache image builds successfully with the required dependencies.
