I was using Unity on Ubuntu 14.04 and was giving me trouble after going dual monitors, so decided to give KDE a try. So I installed KDE by following the commands below found here hoping that I'll get Plasma 5.
sudo apt-add-repository ppa:kubuntu-ppa/backports
sudo apt-get update
sudo apt-get install plasma-desktop
I really like KDE but I have ended up with KDE Plasma 4.x as the --version says below:
$ plasma-desktop -version
Qt: 4.8.6
KDE Development Platform: 4.14.2
Plasma Desktop Shell: 4.11.11
And also here's how IKnfocenter looks:
How do I get Plasma 5.4 (NOT 5.3 as it's unstable from what I read)?
Here https://community.kde.org/Plasma/LiveImages you can download some Live Images of distributions that ship with Plasma 5.
