Linux/Unix notes
If you installed Azureus 3.0.2.0 or higher, you can also try a manual update.
Make sure Azureus is not running
Open up a shell
Change to the azureus program dir
Run "./updateAzureus" (If this is your first time using the script, you may have to "chmod +x ./updateAzureus"). If you don't have this script, you can create one:
sudo java -cp ./plugins/azupdater/Updater.jar org.gudy.azureus2.update.Updater updateonly `pwd` ~/.azureus
Assuming you have a ./plugins/azupdater/Updater.jar, this will elevate your rights and apply any updates that couldn't be done with your normal user's rights.
