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.

  • Its necessary to know what packages you were updating and the error that was showing on the screen afterwards. Can you recall these? Is no key working? – heemayl Nov 14 '14 at 16:41
  • Get into tty console ( Ctrl+Alt+F1 or any other F key ) login there, and read through logs in /var/log directory, namely you'd be interested in dmesg and syslog. Look for errors and warnings. Probably good idea is to mount a usb and copy those to usb, and post them here or ar least portions of them – Sergiy Kolodyazhnyy Nov 14 '14 at 16:52

Get into tty1 console (Ctrl+Alt+F1) and login there.

Type the commands

sudo apt-get update

sudo apt-get -f install

This should install any missing dependencies

  • check with f1-f9, you'll get in at some combo. – Rajesh Rajendran Apr 27 '18 at 2:58
