I "think" that as far as my question goes (or went) wine-stable is the package 
I would install via apt install

No, it was installed via "apt install" before I upgraded from 16.04.5 to 
18.04.1, as it was (and is) in the repository there was no reason to install 
any other way

as the versions seem to be the same is there a "safe" way to insure that future 
updates are installed in the normal way:-

apt update && apt dist-upgrade
