You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies.
 libpython2.7 : Depends: python2.7 (= 2.7.3-0ubuntu3.1) but 2.7.3-0ubuntu3 is to be installed
 python2.7-dev : Depends: python2.7 (= 2.7.3-0ubuntu3.1) but 2.7.3-0ubuntu3 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
