sudo apt install ansible installed version from ubuntu archive instead of ansible ppa.

That's what I tried first (on 18.04), but I subsequently experienced problems which I attributed to that being an old version of Ansible (2.5? not sure). I would prefer to install from ubuntu repos, so maybe we should just explicityl state that the instructions are for 20.04 only.
