If you’re running Kubuntu 22.04 LTS you can now upgrade to KDE Plasma 5.25, the latest stable release of the free, open source desktop environment.
The Kubuntu team has made the update available to install from its backports PPA following requests from users.
To be clear: this is not an automatic upgrade. The Kubuntu 22.04 LTS install image ships with KDE Plasma 5.24 by default, and that’s not changing.
Instead, users who want to upgrade to Plasma 5.25 on Jammy can opt-in by adding the Kubuntu backports PPA and a new backports-extra PPA (technically the extra PPA can be used on its own but the team say it’s designed to be used alongside the standard backports PPA).
“Providing backports of new Plasma versions to a LTS release always must be an ‘opt-in’ process, however we are aware that many of our users now are accustomed to adding our backports PPA as a matter of course, so for a LTS release some additional caution is required in what we make available there,” the team say.
Naturally this extra-curricular task comes saddled with the usual caveats. If you’re using Kubuntu 22.04 LTS because you want maximum stability and quality assurance you probably should stick with the version you’ve got already.
But if you’re competent enough to check proposed updates (to make sure they’re ok) and/or undo the process entirely if something goes wrong, have at it!
To upgrade to Plasma 5.25 on Ubuntu 22.04 LTS just add the backports-extra PPA:
sudo add-apt-repository ppa:kubuntu-ppa/backports-extra
Then, download and install the update:
sudo apt full-upgrade -y
Once everything is in place you just need to reboot your machine and log in to start enjoying all of the great new features in KDE Plasma 5.25.
