You seem to have both the kubuntu-desktop metapackage and the ubuntu-desktop
metapackage installed. Having two metapackages installed can create a
complicated upgrade for the release upgrader and this time it wasn't able to
figure out the upgrade path. I'd suggest removing one of the metapackages and
try the upgrade again. The messages I used to determine this appear in
VarLogDistupgradeMainlog.txt:
