Installing Scribus key

[Helder Terra]

I found out that the new 1.3.9 version of Scribus was released, and since 
I'd made a fresh install of Kubuntu Maverick, I had to import its security 
key again, to add the repository.

But once I entered the "sudo gpg --keyserver wwwkeys.eu.pgp.net --recv-keys 
EEF818CF" into terminal (as shown bleow), I got a response telling me that, 
beacouse of security reasons, I couldn't install the key. I've taken a look 
at gpg.conf and couldn't find where so grant the needed permissions.

I hadn't taht problem with the previous versions of Kubuntu. What should I 
do to solve the problem?
