Settings missing after upgrade to 20.04

Hello!

Today I upgraded from Ubuntu 18.04 LTS to 20.04 LTS (no clean install), and it seemed to be pretty painless. Though, I am now missing the settings app and icon, gnome-control-center. After trying to apt get install gnome-control-center, I get an error with the following output: https://pastebin.com/NGaCYNr9

Things I've already tried:
- sudo apt upgrade
- sudo apt update
- sudo apt install -f
- Restarting

To no avail.

Can anyone help me? Much appreciated!
