I am getting error when running apt-get remove

root@System:~/Downloads# sudo apt-get remove  
The following packages have unmet dependencies:
 libpcap0.8 : Breaks: libpcap0.8:i386 (!= 1.4.0-2) but 1.5.3-2 is installed

E: Unmet dependencies. Try using -f.

and when I ran apt-get remove -f this is what happens:

The solution is simple:

sudo apt-get -f remove libpcap-dev libpcap0.8 libpcap0.8-dev libpcap0.8-dev:i386 libpcap0.8:i386

So, why this happens? You have two version of libpcap0.8 package, one for amd64 and another for i386, which both should be conflicting, but I guess you used a PPA before to install those packages and they didn't have the proper Conflicts fields.

if you have the i386 installed and the amd64 like i did, from ppa. what i did was had to manually remove the file

cd /usr/lib/i386-linux-gnu
  sudo rm libpcap0.8:i386

then run 

sudo apt-get -f install
