How to upgrade Openfire from 3.8.2 to 3.10.0?

Question

When I try to upgrade Openfire from 3.8.2 to 3.10.0, it gives the following error.
I am using Ubuntu 12.04.

1. wget http://download.igniterealtime.org/openfire/openfire_3.10.0_all.deb
2. sudo dpkg -i openfire_3.10.0_all.deb

I have Googled and came up with this link but still no solution.

Answer 1

The thread provided in link states this:

• stop the running OpenFire: sudo /etc/init.d/openfire stop , if it doesn't stop then search and kill its process by sudo kill -9 PID

to get the PID

ps aux | grep openfire

the result would be something like:

maythux   3541  0.4  0.0 613892 18500 ?        Sl   09:17   0:00 blah blah blah

Here the PID is 3541, then to kill this process run the command

sudo kill -9 3541

• delete all plugins (NOT their data directories): sudo rm /var/lib/openfire/plugins/*.jar

• update the old OpenFire using dpkg with the following command:

  sudo dpkg -i openfire_3.10.0_all.deb
  

• if it's not already running, start it again: sudo /etc/init.d/openfire start

• After it runs and get into the admin interface try to re-install the plugins you had, the settings will be retained

• go to Security Settings and make the checkmark at "Accept self-signed certificates. Server dialback over TLS is now available."
