In https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=988089 we went as
far as running apt with:

apt dist-upgrade -o Debug::pkgDepCache::AutoInstall=1 -o
Debug::pkgDepCache::Marker=1 -o Debug::pkgProblemResolver=1

..but this easily gets too verbose. Ideally apt had a mode that if it
fails, it would output a proper error message with a "trace", but in
normal cases stays short and sweet not to clutter the logs too much.
