At first, I got this message: "The disk drive for / is not ready yet or not present" I typed 'M' to run manual recovery in shell.
Next, I tried
chroot / mount -n -o remount,defaults /dev/sda1 / apt-get install -f
I got this off a post, but I have no clue what it means (I'm a total rookie at shell)! After the last command runs, it fails to correct dependencies and ends with these two lines:
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. E: Unable to correct dependencies
What is going on?
