I decided to reinstall apache2, using apt-get remove apache2*, and manually deleting all of /etc/apache2.
Now after I apt-get install apache2, and/or apache2-common, there are quite a few things missing from /etc/apache2, such as apache2.conf and the entire directory mods-available is empty.
I've tried all sorts of things, trying apt-get --reinstall install, installing the subpackages manually, removing it all, but still it's leaving a lot of things out (specifically out of apache2-common, since it's responsible for apache2.conf and the mods folder).
