ipscan is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 ipscan : Depends: openjdk-8-jre but it is not installable or
                   oracle-java8-installer but it is not installable or
                   openjdk-7-jre but it is not going to be installed or
                   oracle-java7-installer but it is not installable or
                   openjdk-6-jre but it is not going to be installed or
                   sun-java6-jre but it is not installable
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
