Ubuntu – How To Install And Test KDE Plasma 5 On Ubuntu 14.04

14.04kdeunity

KDE Plasma 5 is hitting release candidate now: Schedules/Plasma 5 – KDE TechBase.

How can I install plasma 5 in Ubuntu 14.04.

Best Answer

Trusty

Since Dec, 05 2014, project neon is no more available as a PPA, unfortunately.

Utopic

Utopic is shipped with Plasma 4. If you want Plasma 5 there is a KDE Next PPA (which will provide updated KDE too), but it'll replace the current installed KDE

Install

sudo apt-add-repository ppa:kubuntu-ppa/next
sudo apt update
sudo apt install kubuntu-plasma5-desktop
sudo apt full-upgrade

And finally, after save all your work:

sudo reboot

Sources

Kubuntu CI: the replacement for Project Neon - blogs.kde.org
Frameworks/Binary Packages - KDE Community Wiki

ppa:kubuntu-ppa/next-backports is a valid name for a PPA, but there is no PPA with this name. Here is a list of valid PPAs of the “Kubuntu Package Archives” team.

backports – Kubuntu Backports
beta – Kubuntu Beta Backports
experimental – Kubuntu Experimental
ppa – Kubuntu Updates
staging-frameworks – Kubuntu Staging Frameworks
staging-kdeapplications – Kubuntu Staging KDE Applications
staging-misc – Kubuntu Staging Misc
staging-plasma – Kubuntu Staging Plasma

Therefore install an existing PPA, e.g.

sudo apt-add-repository ppa:kubuntu-ppa/backports
