Unmet dependencies on Debian

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

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.

Answer 2

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 ;)
