Unmet dependencies on Debian - apache

Question

I have unmet dependencies for libapache2-mod-php7.0. In my attempt to fix this issue I have been playing around with my sources and have done a variety of upgrades. I was on Stretch when I started, I know I've probably gone about it the wrong way but I like to try before I ask.

What else can I try to resolve this?

Answer 1

you need to remove apache
apt-get remove apache2.2-bin
you can force the installation of apache2-bin:
dpkg -i --force-overwrite /var/cache/apt/archives/apache2-bin_2.4.20-2_amd64.deb
and then try
apt-get -f install
for me it worked ;)

Answer 2

Try these steps
1. sudo apt-get update
2. sudo apt-get dist-upgrade
3. apt-get install -f --reinstall apache2
-f to fix unmet dependencies.
