How can I fix dependency problems in Ubuntu 16.04?

Question

I'm trying to install Ring and have run into dependency problems. I have no idea how to fix this. Would you have any ideas about how to approach this problem? I have attempted sudo apt-get update, sudo apt-get autoremove and sudo apt-get -f install but nothing seemed to help.
