Uninstall this.  See reasons listed in my previous email.

and what happened?  Did it work?

Forget about the repository.  See reasons listed in my previous email.

Upgrades are easy.  You just download and install the new version along side 
your existing version, migrate your config from the old to new version (use a 
diff tool or [1]) and deploy your apps to the new instance.  More info on 
upgrades can be found here [2].

While it's a bit more complicated to initially setup, you can streamline the 
upgrade process further by using separate CATALINA_HOME and CATALINA_BASE 
environment variables.  For more info on how to do this, see the "Advanced 
Configuration - Multiple Tomcat Instances" in RUNNING.txt.

You should look at RUNNING.txt [3].  It's not a pretty HTML page, but it says 
exactly what you need to know about installing.  The only part missing from 
RUNNING.txt would be instructions for installing as init.d script to start on 
boot.  This is documented here [4].

  [4] - https://tomcat.apache.org/tomcat-6.0-doc/setup.html#Unix_daemon

Finally, if you have any specific questions about installing or upgrading, or 
encounter any problems while trying, just ask on the list.  For best results, 
include as much detail about your question / problem as possible.  Include OS, 
full Tomcat version, logs, full error message or anything else relevant to the 
problem.
