In KDE update why blocked updates

[mastergunner]

In 9.04 there is a KDE software update. I get all the upgrades but there is always 4 blocked updates. How can i download those updates if they are blocked or what am I doing wrong? Thanks for any help.

sudo aptitude
u
U
g
q
y

That does not work. Exactly what sources should I have. Maybe something is wrong with them.
