It worked!!! Thank you @dbrand666, unfortunately now I am stuck in perpetual “Preparing Home Assistant.” In its long script at the end it reads: “23-01-23 18:06:06 WARNING (MainThread) [supervisor.homeassistant.core] Error on Home Assistant installation. Retry in 30sec”
BTW, this is my third installation of HAOS.
May go now to: Installing Home Assistant Supervised on Debian 11
