How do we update fail2ban when updates are made?

http://issues.freepbx.org/browse/FREEPBX-11575 speaks to a problem I just dealt with on the one PBX where I was using PJ-SIP. How do I update fail2ban so that it stops this particular problem so that I can re-enable it? I haven’t updated any modules in a few days, and noticed that we’d solved the problem I was about to scream about last week.
