Agreed. Though, this case we are taking about upgrading versions of maas,
where the ''maas' package still remains as a transtional/virtual package
that pulls the dependencies. The reason why I wanted it not to conflict
with an older version of MAAS is mainly because of the DB, since its
creation/removal is handled by dbconfig-common itself. I can certainly look
into using breaks/replaces and the results of using it further along the
way,

Right, this might be an issue with dbconfig-common then.

Indeed, and this is an issue I had raised that we weren't able to address
like cycle.

probably a better solution (in terms of policy), while 2 is a much simpler
one.
