So what do you suggest? Adding Breaks instead of Conflicts? The facts
are that we cannot have tex-common >= 2 with old TeX Live, and at
the same time new TeX Live with old tex-common, both are combinations
ripe for breakage.
cupt *should* be able to deal with these situations, they for sure
happened already several other times (I didn't verify, but I guess
that one of the big X, Gnome, KDE transitions had similar problems).

Yes, and the Conflicts we have *are* correct. What is not correct is
cupt as it does not find the solution to upgrade both removing one
temporarily.

Right, or the next time we have a big TL transition it will happen
again with cupt.

EXETER (n.)
All light household and electrical goods contain a number of vital
components plus at least one exeter. If you've just mended a fuse,
changed a bulb or fixed a blender, the exeter is the small, flat or
round plastic or bakelite piece left over which means you have to undo
everything and start all over again.
