to day I have installed the new Kubuntu 9.04 as suggested from the web,
immediately I faced two problems:

1. The system (a laptop Dell) did not allow me to connect to the web,
this in spite of the fact that the network set up for the wireless
connection was properly set.
2. The USB connection through an external key was no longer possible
(key was not even seen by the system).

Does anybody has any idea? Have I done something wrong or the new
version creators had forgotten something?
