I would try 

	sudo apt-get install mysql-client, mysql-server, mysql-server-core

and check that the list of packages it says it will upgrade is what you
want.  That *should* do waht you want.  (If not, say 'n' :)

Depending on your reasoning for not wanting to upgrade the other
packages, you also may want to pin the existing versions of those
packages.  (I don't keep systems around long enough to know how
to really do that without looking it up every time)
