We currently have Plasma 5.24.90 (Plasma 5.25 Beta)  available in our Beta PPA for Kubuntu 22.04, and in the Ubuntu archive and daily ISO build for the 22.10 development series.

However this is a beta release, and we should re-iterate the disclaimer from the upstream release announcement:

DISCLAIMER: Today we are bringing you the preview version of KDE’s Plasma 5.25 desktop release. Plasma 5.25 Beta is aimed at testers, developers, and bug-hunters. To help KDE developers iron out bugs and solve issues, install Plasma 5.25 Beta and test run the features listed below. Please report bugs to our bug tracker. We will be holding a Plasma 5.25 beta review day on May 26 (details will be published on our social media) and you can join us for a day of bug-hunting, triaging and solving alongside the Plasma devs! The final version of Plasma 5.25 will become available for the general public on the 14th of June. DISCLAIMER: This release contains untested and unstable software. It is highly recommended you do not use this version in a production environment and do not use it as your daily work environment. You risk crashes and loss of data.

Testers of the Kubuntu 22.10 Kinetic Kudu development series:

Testers with a current install can simply upgrade their packages to install the 5.25 Beta.

Alternatively, a live/install image is available at: http://cdimage.ubuntu.com/kubuntu/daily-live/current/

Users on Kubuntu 22.04 Jammy Jellyfish:

5.25 Beta packages and required dependencies are available in our Beta PPA.

The PPA should work whether you are currently using our backports PPA or not.

If you are prepared to test via the PPA, then…..

Add the beta PPA and then upgrade:

sudo add-apt-repository ppa:kubuntu-ppa/beta && sudo apt full-upgrade -y

Then reboot.

In case of issues, testers should be prepared to use ppa-purge to remove the PPA and revert/downgrade packages.

Kubuntu is part of the KDE community, so this testing will benefit both Kubuntu as well as upstream KDE Plasma software, which is used by many other distributions too.

• If you believe you might have found a packaging bug, you can use launchpad.net to post testing feedback to the Kubuntu team as a bug, or give feedback on IRC [1], or mailing lists [2].
• If you believe you have found a bug in the underlying software, then bugs.kde.org is the best place to file your bug report.

Please review the release announcement and changelog.

[Test Case]
* General tests:
– Does plasma desktop start as normal with no apparent regressions over 5.24?
– General workflow – testers should carry out their normal tasks, using the plasma features they normally do, and test common subsystems such as audio, settings changes, compositing, desktop affects, suspend etc.
* Specific tests:
– Check the changelog:
– Identify items with front/user facing changes capable of specific testing.
– Test the ‘fixed’ functionality or ‘new’ feature.

Testing may involve some technical set up to do, so while you do not need to be a highly advanced K/Ubuntu user, some proficiently in apt-based package management is advisable.

Testing is very important to the quality of the software Ubuntu and Kubuntu developers package and release.

We need your help to get this important beta release in shape for Kubuntu and the KDE community as a whole.

Thanks!

Please stop by the Kubuntu-devel IRC channel on libera.chat if you need clarification of any of the steps to follow.

To update, use the Software Repository Guide to add the following repository to your software sources list:

ppa:kubuntu-ppa/backports

or 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/backports

and packages then updated with

sudo apt update
sudo apt full-upgrade

Upgrade notes:

~ The Kubuntu backports PPA already contains significant version upgrades of Plasma, applications, Frameworks (and Qt for 16.04), 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 the versions in this announcement.  The PPA will also continue to receive bugfix and other stable updates when they become available.

~ 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], file a bug against our PPA packages [3], or optionally contact us via social media.
