I saw in your dist-upgrade/apt-term.log file (first column are line numbers):
7245 Setting up libapache2-mod-php7.3 (7.3.11-0ubuntu0.19.10.1) ...
7247 Creating config file /etc/php/7.3/apache2/php.ini with new version
7248 libapache2-mod-php7.3: php7.2 module already enabled, not enabling PHP 7.3
and later
7860 Removing libapache2-mod-php7.2 (7.2.24-0ubuntu0.19.04.1) ...
7861 Module php7.2 disabled.
7862 apache2_invoke prerm: Disable module php7.2
It might be an ordering issue needing 7.2 removed before 7.3 is installed to avoid this?
