Updating Azureus

When I have problems with Azureus I update it with the latest version and it usually gets fixed. The only thing you have to do is replace the Azureus.jar file like this:
Download the newest Azureus.jar (currently, it's here)

Once you have saved it in a folder called, say, "Downloads", you do this in a Terminal:

Backup your old Azureus.jar:

sudo cp /usr/share/java/Azureus2.jar /usr/share/java/Azureus2.jar.bak

Then remove the old version:

sudo rm /usr/share/java/Azureus2.jar

Then copy the newest version to where it should be:

sudo cp Downloads/Azureus2.5.0.4.jar /usr/share/java/Azureus2.jar
