Darn. I guess it's not as simple as that. Go to System Settings → Synaptic
Package Manager, click on the "Broken Dependencies" option on the side menu,
and mark all the listed packages for removal.
Installation of Replicant was trivial for me once I got the 32-bit libraries
installed, so I'm determined to help you get through this. I'll try to walk
you through the process of what allowed me to install Replicant.
Download this script and move it to your home folder: ia32-bypass.txt
sudo apt-get -f install libsdl1.2debian openjdk-6-jdk
bash ia32-bypass.txt
sudo apt-get install ia32-libs
After that, follow the three-step procedure I described above. This worked
for me; I hope it will do the same for you.
