[ubuntu-za] Update error

[Wikus]

Morning everyone ,

I get the following error in update manager :

Now I assume the error is because there is more than one Java that wants 
to update.
This has never happened before since I started using 12.04 since launch. 
Now is the first time this
happened.

1. Why does this happen ?
2. How do I fix it ? I don't know which JDK there to choose to update 
and also what to do to avoid this happening in the
future

Ubuntu 12.04.1 32bit with all updates until today.

Thanx
