Comment 2 for bug 1890263

Hmm. Yes, seems pretty straightforward to reproduce the problem in
lxc. At the end of the upgrade it offers to remove mod php 7.2:

Reading state information... Done

Remove obsolete packages?

69 packages are going to be removed.

 Continue [yN] Details [d]d

Remove: libapache2-mod-php7.2

Remove (was auto installed) acl acpid btrfs-tools
  command-not-found-data dns-root-data dnsmasq-base ebtables
  gcc-8-base geoip-database libbind9-160 libdns-export1100 libdns1100

  php7.2-opcache php7.2-readline python3-asn1crypto python3-pam
  python3.6 python3.6-minimal uidmap ureadahead xdelta3

I wonder if there needs to be a dependency added for the
libapache2-mod-php virtual package.
