openfire is an older package that relies on an older java (sun-java5-jre | sun-java6-jre), the new java bundled with ubuntu is "default-jre-headless"  based on openjdk.

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 openfire : PreDepends: sun-java5-jre but it is not installable or
                        sun-java6-jre but it is not installable
 php5-cli : Depends: php5-common (= 5.3.3-1ubuntu9.3) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).


This is driving me crazy that openfire's dependencies which I said "ignore" when I installed it are coming back now breaking me from installing new stuff.

Thoughts?
