Yesterday I was updating some applications. I come back later and I see a red stop sign on top of my screen that stated there was an error. It said that some of my packages needed some dependencies. I ignored it and shut off my laptop. Now Ubuntu starts up and takes me to my login screen but freezes. I can't move the mouse or type in my password. Does anyone know how I can fix this?
I hope this was clear enough, I'm a newbie with ubuntu. I have a 2012 macbook pro 15inch.
