In looking at the postinst script /var/lib/dpkg/info/libapache2-mod-security2.postinst, it appears that it is trying to enable the "security2" module, but that module does not exist in /etc/apache2/mods-available, so I don't think it will ever succeed. If you modify that script so that chunk is a no-op, it will succeed and "work", allowing installation of other packages to continue. I don't yet know if there are bad side-effects as I would expect that module to exist.

I commented out the "apache2_invoke..." line and added 'echo "Disabled stuff here"' to make bash happy.

It looks like there are quite a few changes with apache2 and it's modules between 14.04 and 16.04, so this workaround may break all the things. Proceed with caution.

Yeah, my workaround to get my server back up was to just uninstall all the affected modules, since I wasn't really using them anyway.
