Comment 8 for bug 1850933

I have myself created a 19.04 system with:
- libapache2-mod-php + libapache2-mod-php7.2
  - as expected on configure does this automatically
  - This is from /var/lib/dpkg/info/libapache2-mod-php7.2.postinst
     php_invoke enmod 7.2 apache2 $mod
- Created the most trivial PHP (index.php with phpinfo in /var/www/html/index.php
  - Upgraded from 19.04 to 19.10
  - Confirmed to hit the described isse

# ll /etc/apache2/mods-available/*php* /etc/apache2/mods-enabled/*php*
ls: cannot access '/etc/apache2/mods-enabled/*php*': No such file or directory
-rw-r--r-- 1 root root 855 Oct 24 11:38 /etc/apache2/mods-available/php7.3.conf
-rw-r--r-- 1 root root 102 Oct 24 11:38 /etc/apache2/mods-available/php7.3.load

And the server now serving the PHP code.
