Plasma/InstallingNext
How to install test versions of Plasma Next
Kubuntu
Packages for Kubuntu Vivid Next and Next backports PPAs for Utopic (15.04) are now deprecated and beyond end-of-life. The present release is Wily, 15.10.
To test upgrade to Xenial, which will be released in April 2016, please use the PPA-purge package to remove PPAs and packages from PPAs, and install `kubuntu-desktop` meta-package, and finally:
sudo apt update && sudo apt full-upgrade
before initiating:
sudo devel-release-upgrade -d
to move to Xenial. Instructions for moving to the beta will be given here once it is released.

openSUSE
openSUSE offers snapshots from git master updated frequently as well. Add the KDE:Unstable:Frameworks repository (http://en.opensuse.org/SDB:KDE_repositories#Plasma_Next) and the Qt53 repository (available at the same link) and install the plasma-next-session package to have a session available at the next login.
Gentoo
Gentoo provides beta as well as live ebuilds inside kde overlay, with dependencies in qt overlay. The following assumes you have a basic understanding of Gentoo Portage and already set up layman initially:
layman -a kde && layman -a qt
emerge @kde-next-live --autounmask-write=y
To make the most of it, run
layman -S && smart-live-rebuild
to get the latest packaging changes for qt and kde and update any live packages that got new commits since last time.

Fedora
Now that Plasma 5 has been released, Fedora packaging only tracks the official Plasma 5 releases, not snapshots. See Plasma/Packages#Fedora for installation instructions.
Arch
Plasma 5 workspace is available through the official repositories. For the full installation, simply install plasma-next.
Frameworks 5 libraries are also in the official repositories under kf5 and kf5-aids.
There are git versions of the above, as well as many other Frameworks 5 applications installable through the AUR.
See the KDE page on the ArchWiki for more information.
From Source
Following the instructions here it will automatically build all KDE software that has a KF5 port, most notably the Plasma workspaces, but also development previews of Kate, Konsole and Dolphin.
Afterwards follow the guides for "Runtime setup" and then run "kwin --replace" and "plasmashell".
