How to install test versions of Plasma Next


Packages for Kubuntu Utopic Next and Next backports PPAs for Utopic (14.10) are now deprecated.

To test upgrade to Vivid, please use the PPA-purge package to remove those PPAs and packages, and then install `kubuntu-desktop` meta-package, and finally:

sudo apt update && sudo apt full-upgrade

before initiating:

sudo kubuntu-devel-release-upgrade

to move to Vivid beta. Full instructions to upgrade from 14.10.

Live Image of Kubuntu Vivid with Packages from Git The Weekly Live Image, updated every Friday with latest source from Git to run a full system from a USB disk. Based on Kubuntu 15.04, Vivid.

KDE Frameworks 5 and Plasma 5 is available in the Vivid development version of Kubuntu, now in beta.


openSUSE offers snapshots from git master updated frequently as well. Add the KDE:Unstable:Frameworks repository ( 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 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.

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.


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.


Right now the latest installation disks of siduction (indiansummer release) are providing KDE SC 4.x, however you can upgrade from your KDE SC 4 installation to KDE Frameworks + Plasma 5 + KDE Applications using the kdenext repository. You can also install KDE's Plasma 5 from stcratch and you can install Plasma 5 if you are using a non-KDE flavour of siduction, like "siduction lxde", see below.

To install Plasma 5 from scratch:

To upgrade from KDE SC 4 to Frameworks + Plasma 5 + latest KDE Applications:

  • In a siduction installation with KDE SC 4, add the unstable and kde-frameworks suite of the kdenext repository to your sources.list:
deb unstable main
  • Perform a dist-upgrade.
  • It's recommended to install either kde-standard or kde-full (whichever you prefer) after the upgrade.
  • If you find issues with the upgrade (such as apt-get/aptitude wanting to remove packages which shouldn't be removed) please use the siduction forum to report the issue.

To install KDE's Plasma 5 in a non-KDE siduction flavour:

  • Add the kde-frameworks suite of the kdenext repository to your sources.list:
deb unstable main
  • Install either the package kde-standard or kde-full, whichever you prefer. After that you are suposed to be able to run plasma 5, no matter the login manager you are using.

To replace the old kdm with other login manager:

The old kdm login manager is obsolete and is going to be removed from our repositories sooner or later, so we recommend you to switch to lightdm (the default login manager in siduction) or if you are a bit more adventurous to sddm.

  • To switch to lightdm:

Install the lightdm settings for your release, this will install lightdm automatically; when asked, select lightdm as the default login manager. If you are using indiansummer:

 apt-get install siduction-settings-lightdm-gtk-indiansummer

If you are using the december release:

 apt-get install siduction-settings-lightdm-gtk-december

If you are using a release which is not december nor indiansummer, you should install the indiansummer settings.

  • To swtich to sddm
apt-get install sddm kde-config-sddm

And select sddm as default login manager when asked.

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".
