Bug#727082: apt: dist-upgrade says "no longer required" and "will be installed" for the same packages

This shows a "display bug" – there shouldn't be code printing stuff between
"Calculating upgrade…" and "Done", but it looks like the recent reshuffling of
code made it happen.

This should be the reported problem itself.

I presume you have 0.19.2-1 installed and apt is trying to upgrade you to
0.24.3-1, but decides against it because of $REASON.

I can construct a testcase here with conflicting packages as $REASON,
but I guess your $REASON is different which would be interesting to know
so that we can cover all bases. Running:
$ apt-get dist-upgrade -s -o Debug::pkgProblemResolver=1 -o
Debug::pkgDepCache::Marker=1 -o Debug::pkgDepCache::AutoInstall=1
should print a bunch of stuff telling us what the $REASON is.
