libc6 is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 libc6 : Breaks: libc6:i386 (!= 2.15-0ubuntu10.6) but 2.15-0ubuntu10.5 is to be installed
 libc6:i386 : Depends: libc-bin:i386 (= 2.15-0ubuntu10.5)
              Breaks: libc6 (!= 2.15-0ubuntu10.5) but 2.15-0ubuntu10.6 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
