cant disable third-party repositories for upgrade

Question

I Can't disable third-party repositories for upgrading.

I've tried everything including "software and updates" [other software] checked off all. Also tried apt-get install -fas terminal suggests. also tried sudo software-properties-gtk

This is what keeps coming up no matter what I try.

Errors were encountered while processing:

The package system is broken

Check if you are using third-party repositories. If so, disable them, because they are a common source of problems.
Furthermore, run the following command in a Terminal: apt-get install -f

Please help.

Answer 1

Remove all files from /etc/apt/sources.list.d:

mkdir ~/sources.list.d
sudo mv /etc/apt/sources.list.d ~/

Remove

sudo mv /etc/apt/sources.list ~/

Start software-properties-gtk

gksudo software-properties-gtk

Check the following properties (sorry for vivid in my screenshots). Thus, the file /etc/apt/sources.list is created again.

Install aptitude

sudo apt-get install aptitude

and run with

sudo aptitude install -f

and fix your problems.
