You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 libgssapi-krb5-2 : Depends: libkeyutils1 but it is not going to be installed
 libk5crypto3 : Depends: libkeyutils1 but it is not going to be installed
 libkrb5-3 : Depends: libkeyutils1 but it is not going to be installed
 libkrb5support0 : Depends: libkeyutils1 but it is not going to be installed
 openssh-server : Depends: libwrap0 (>= 7.6-4~) but it is not going to be installed
                  Depends: openssh-client (= 1:6.0p1-4+deb7u2) but it is not going to be installed
                  Recommends: ncurses-term but it is not going to be installed
                  Recommends: openssh-blacklist but it is not going to be installed
                  Recommends: openssh-blacklist-extra but it is not going to be installed
