"a problem occurred when checking for updates" error

Question

I've already tried doing what was listed here: Update manager: "A problem occurred when checking for the updates" but it didnt work.

Every time I click on the red circle with the line through it the update manager pops up and then goes away.

When I try to do sudo apt-get update && sudo apt-get upgrade

here's the output:

So, you are aborting at 50% of building.

Try this: (attempt to correct broken dependencies)

sudo apt-get upgrade -f

I'm still getting the same thing, it didn't change, I'm not purposely aborting. as soon as it reaches 50% it does this: Reading package lists... Done alex@griever:~$ ncy tree... 50% and cuts off the dependency tree word and stays at 50

Did you try the update -f or upgrade -f commands?

I clicked update and it gave me the following: The package system is broken Check if you are using third party repositories. If so disable them, since they are a common source of problems. Furthermore run the following command in a Terminal: apt-get install -f

Add output (to your question) for cat /etc/apt/sources.list

Turns out all I needed to do was apt-get clean :) Thank you all for your help.

It looks like it ran sudo apt-get update OK but then skipped the sudo apt-get upgrade part. Try running sudo apt-get upgrade again, post any exact errors you may get.
