Title:
  Dependency error installing fontconfig-dbgsym

Status in fontconfig package in Ubuntu:
  Invalid

Bug description:
  I am trying to install fontconfig-dbgsym under Ubuntu 18.04 inside
  Docker, running on Docker for Mac.

  I use the following Dockerfile:

      FROM ubuntu:18.04
      ENV DEBIAN_FRONTEND=noninteractive
      RUN apt-get update
      RUN apt-get install -y ubuntu-dbgsym-keyring lsb-release
      RUN \
      	( \
      		echo "deb http://ddebs.ubuntu.com $(lsb_release -cs) main restricted universe multiverse"; \
      		echo "deb http://ddebs.ubuntu.com $(lsb_release -cs)-updates main restricted universe multiverse"; \
      		echo "deb http://ddebs.ubuntu.com $(lsb_release -cs)-proposed main restricted universe multiverse"; \
      	) > /etc/apt/sources.list.d/ddebs.list 
      RUN apt-get update
      RUN apt-get install -y fontconfig
      RUN apt-get install -y fontconfig-dbgsym

  Everything works except the last step, which fails with:

      Reading package lists...
      Building dependency tree...
      Reading state information...
      Some packages could not be installed. This may mean that you have
      requested an impossible situation or if you are using the unstable
      distribution that some required packages have not yet been created
      or been moved out of Incoming.
      The following information may help to resolve the situation:
      
      The following packages have unmet dependencies:
       fontconfig-dbgsym : Depends: fontconfig (= 2.12.6-0ubuntu2.2) but 2.12.6-0ubuntu2 is to be installed
      E: Unable to correct problems, you have held broken packages.
      The command '/bin/sh -c apt-get install -y fontconfig-dbgsym' returned a non-zero code: 100

  It complains the dependency `fontconfig=2.12.6-0ubuntu2.2` isn't
  installed, but it was successfully installed by the previous step.

  This looks like a bug.
