haproxy-16 (and 19) charms fail deployment in Juju 2.0 with "hook "config-changed" failed" error

[Dario Molinari]

Tried deploying landscape-maas-dense bundle on LXD containers on both bare metal and virtual machines but charm haproxy (16 and 19) consistently fails with "hook "config-changed" failed"

unit-haproxy-1.log attached:
