Upgrade to KDE 4.5.1 - How I did it

[Snowhog]

This is very short, but it was what I did, and it went flawlessly.

Steps:
1. Add the KDE 4.5.1 Repository
(see Kubuntu Backports)
2. Open a console and and type:

sudo apt-get update
sudo apt-get dist-upgrade

3. Perform a system restart (reboot your PC).
4. Open a console and type:

sudo apt-get update

If you get any errors, then type:

sudo apt-get -f install

Otherwise perform a system restart (reboot your PC).
5. Open a console and type:

sudo apt-get update
sudo apt-get dist-upgrade

6. Perform a system restart (reboot your PC).
7. Open a console and type:

sudo apt-get update
sudo apt-get dist-upgrade

I followed these steps after a fresh install of Kubuntu 10.04, which came with KDE 4.4.2. It went flawlessly. YMMV. (IF IN DOUBT, BACKUP FIRST!)

There are lots of restart, are they necessary?

Maybe, maybe not. But, as I said, this is how I did it, and I had zero issues. I like zero issues.

In my experience, a reboot is only necessary when the upgrade installs a new kernel.
A log out and log back in is necessary when a new video driver was installed (or, you can open a konsole and do "sudo service kdm restart").

No. You don't need to use the command line either, Synaptic works fine (just don't use KPackageKit!)
Simply add the Kubuntu backports repository in Synaptic, click Reload, then Mark All Upgrades, then Apply. Let it download and install anything, and when it's done, reboot. That's all. Zero issues with that for me.
