TBH I'm not that familiar with Tomcat but having a quick look it seems that it should install ok. Did you run 'apt-get update' first?
Perhaps there is something already broken on your system? Try running 'apt-get install -f' (with no package names).
Perhaps you need to uninstall tomcat6 first? I'm not sure... 'apt-get remove tomcat6'
FWIW we are working on the new v14.0 appliance range ATM and for that the Tomcat appliance will include Tomcat 7 by default. We don't have an ETA for v14.0 but should be within the next few months. If you want new and security updates regarding TurnKey please signup to our Security and News Announcements (top left of this page).
