我在Ubuntu 14.04上无法使用apt-get安装任何东西

Question

The first problem is that I can't even post my question on askUbuntu!

Second, my problem is, I can't install anything since a while via apt-get , I suspect it happened when I tried to install Deeping desktop a couple of days ago, I modified the repositories somewhere and I forgot where, and compiz is causing the problem. I tried all what I found here, but nothing worked. I found this:

sudo -i
apt-get clean
cd /var/lib/apt
mv lists lists.old
mkdir -p lists/partial
apt-get clean
apt-get update

But, it didn't work.

Here's what I get, when I try to install JAI for example:

sudo apt-get install libjai-core-java

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 compiz : Depends: compiz-core (>= 1:0.9.11.2+14.04.20140714-0ubuntu1) but it is not going to be installed
          Depends: compiz-plugins-default (>= 1:0.9.11.2+14.04.20140714-0ubuntu1) but it is not going to be installed
          Depends: compiz-gnome but it is not going to be installed
 libcompizconfig0 : Depends: compiz-core (= 1:0.9.11.2+14.04.20140714-0ubuntu1) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Afterwards, when I use apt-get -f install , I get this:

Ok, I fixed it. I replaced Saucy by trusty in
