How to upgrade KDE 4.0 apps to KDE 4.1 on Ubuntu 8.04 Hardy

[Ashish Yadav]

I guess my way of doing things are vary different from what people usually do.

For first I have Ubuntu 8.04 and use Gnome as my Desktop Environment.
Though as I do like some applications like Kate, Konsole and (now)
Dolphin, I got them installed based on KDE 4.0.

Now I don't have a option to login and use KDE as my DE, however I can
still use KDE applications while being in Gnome desktop ( I don't care
about consistency in looks, what matters to me is usability according
to my preferences).

Now I don't want to install everything as I have set aside rather
conservative amount of disk space for Ubuntu.

To answer the question, of whether installing KDE 4.1 libs will
effectively means installing KDE 4.1 is that that there is difference
between installing KDE 4 as a desktop environment and installing KDE 4
applications individually, which as I said above is not installing
everything.

So I just wanted to update Kate, Konsole, Dolphin and KDE libs into
their respective KDE 4.1 versions.

What I had done in time in between is to add "deb
http://ppa.launchpad.net/kubuntu-members-kde4/ubuntu hardy main" in
the list of software sources though "Software Sources", and just run
"Update Manager". Upon running "Update Manager" it offered me to
upgrade KDE libs, Kate, Konsole and Dolphin along with their
dependencies to KDE 4.1 versions. Though it warned me that some
packages are not autheticated, which I guess is because of them not
being in list of "Trusted software providers" under "Authentication"
tab in "Software Sources".

For now I ignored it ( GOD save me :-) ) and now I have Kate, Konsole,
Dolphin based on and along with KDE 4.1 libs. As of now they all are
working fine.

However is there a way get the key files for the Kubuntu repositories?
I searched at Kubuntu.org and Google but hadn't found a way.
