Users of Kubuntu 17.10 Artful Aardvark can now upgrade via our backports PPA to the 3rd bugfix release (5.12.3) of the Plasma 5.12 LTS release series from KDE.
(Testers of 18.04 Bionic Beaver will need to be patient as the Ubuntu archive is currently in Beta 1 candidate freeze for our packages, but we hope to update the packages there once the Beta 1 is released)
The full changelog of fixes for 5.12.3 can be found here.
This includes an impressive list of fixes for Plasma Discover software centre, thanks in part to the excellent recent drive to improve and polish this important part of the plasma desktop by our Product Manager and KDE Developer Nate Graham.
Users of 17.10:
To update add the following repository to your software sources list:
ppa:kubuntu-ppa/backportsor if it is already added, the updates should become available via your preferred update method.
The PPA can be added manually in the Konsole terminal with the command:
sudo add-apt-repository ppa:kubuntu-ppa/backportsand packages then updated with
sudo apt update
sudo apt full-upgrade
PPA upgrade notes:
~ The Kubuntu backports PPA includes various other backported applications, and KDE Frameworks 5.43, so please be aware that enabling the backports PPA for the 1st time and doing a full upgrade will result in a substantial amount of upgraded packages in addition to Plasma 5.12.
~ The PPA will also continue to receive bugfix updates to Plasma 5.12 when they become available, and further updated KDE applications.
~ While we believe that these packages represent a beneficial and stable update, please bear in mind that they have not been tested as comprehensively as those in the main Ubuntu archive, and are supported only on a limited and informal basis. Should any issues occur, please provide feedback on our mailing list [1], IRC [2], and/or file a bug against our PPA packages [3].
