When there's some kind of conflict during a package installation
or upgrade, the first solutions proposed by aptitude almost
invariably involve large numbers of package removals. The
simple solution that upgrades/installs what can be and leaves
the rest alone is usually there but buried under at least three
-- and sometimes tens of -- very disruptive ones.
If aptitude got it wrong half the time, it might be for want of
reading minds. But in my experience it gets it consistently
wrong. Suggests to me that what it needs is new heuristics.
