You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
libc6 : Depends: libc-bin (= 2.15-0ubuntu9) but 2.15-0ubuntu7 is installed
libstdc++6 : Depends: gcc-4.6-base (= 4.6.3-1ubuntu4) but 4.6.3-1ubuntu5 is installed
libstdc++6-4.6-dev : Depends: libstdc++6 (>= 4.6.3-1ubuntu5) but 4.6.3-1ubuntu4 is installed
E: Unmet dependencies. Try using -f.

apt-get update

apt-get install -fy
dpkg -i /var/cache/apt/archives/*.deb

apt-get install -fy
apt-get dist-upgrade
