Submitting a Bug on Launchpad when there are Missing Debug Packages?

Question

I submitted a bug report to Launchpad using Apport. Shortly after, I received the following email:

Thank you for your report!

However, processing it in order to get sufficient information for the developers failed (it does not generate a useful symbolic stack trace). This might be caused by some outdated packages which were installed on your system at the time of the report:

outdated -dbg package for libdrm-radeon1: package version 2.4.91-2~16.04.1 -dbg version 2.4.70-1~ubuntu16.04.1
no debug symbol package found for libboost-filesystem1.58.0
outdated -dbg package for libdrm-nouveau2: package version 2.4.91-2~16.04.1 -dbg version 2.4.70-1~ubuntu16.04.1
no debug symbol package found for libcairo-gobject2
no debug symbol package found for libboost-system1.58.0
outdated -dbg package for libdrm2: package version 2.4.91-2~16.04.1 -dbg version 2.4.70-1~ubuntu16.04.1
outdated -dbg package for libwayland-cursor0: package version None -dbg version 1.9.0-1
outdated -dbg package for libdrm-amdgpu1: package version 2.4.91-2~16.04.1 -dbg version 2.4.70-1~ubuntu16.04.1
no debug symbol package found for libogg0
no debug symbol package found for libatk1.0-0
outdated -dbg package for libwayland-client0: package version None -dbg version 1.9.0-1

Please upgrade your system to the latest package versions. If you still encounter the crash, please file a new report.

The problem is that I have checked in Synaptic, and all of the packages referred to either don't exist, or the debug package is out-of date (and there isn't a new one that matches the main package). Can someone advise as to how I can submit this bug report, please?

I have read the page about ApportRetracingService on the Community Help Wiki. It accurately describes the situation I am in, but offers no help on how to remedy it!
