I take that back, and apache 503 issue solved - /etc/apcache2/conf-available/php7.4-fpm.conf is not purged during/after upgrade.

$ sudo cat /var/log/apache2/error.log

Works as expected, except may need to change

AllowOverride None
to
AllowOverride [your settings of choice]

in /etc/apache2/apache2.conf for .htaccess to be honoured.

HTH someone.
