When I try to install s2e in my Ubuntu 12.04, there is a weired problem happens. It give the following error message when I try to install some of the libraries. Google directed me to the following solution, which worked perfectly for me.

Solution
First a downgrade is required and done with the following: create the ‘preferences’ file:
1sudo vi /etc/apt/preferences
and insert the following lines:
enter :wq to write the file. Pin-Priority must be greater than 1000.
Then you may downgrade the offending applications with:
1sudo apt-get dist-upgrade
Then you may install packages that complained about dependencies, like sudo apt-get install ia32-libs-multiarch, or sudo apt-get install ia32-libs.
Finally, you should remove the file you just created:
1sudo rm /etc/apt/preferences
because else no new updates would be found.
