The Kubuntu Backports Extra PPA contains "extra backports, in addition to those in our normal backports PPA" (Kubuntu Backports PPA).

You can find the installation instructions on the Kubuntu Backports PPA and Kubuntu Backports Extra PPA websites, but here they are again (for Backports Extra only - for Backports see Kubuntu Backports PPA):

Open the Konsole terminal emulator and enter
sudo add-apt-repository ppa:kubuntu-ppa/backports-extra
sudo apt update
sudo apt full-upgrade
reboot

After this any future updates that the Kubuntu Backports Extra PPA provide for your Kubuntu version will be automatically installed when you update your system.


As always I strongly recommend that you have prepared some way to revert your system to a previous state if something goes wrong, e.g.:

One can install ppa-purge before and use it to get rid of the Kubuntu Backports' packages again.
Or use a Timeshift system backup.
Or use LVM/ext4 with snapshots or btrfs with snapshots as your file system.
Or use a Clonezilla volume backup.
Or …

Plasma 5.27 has some advantages compared to 5.24 (and it is the last of the 5 series - and is still supported by KDE until next year).

AFAIK we all have to thank acheron for this - I think he is the main maintainer of the Kubuntu Backports projects and certainly puts a lot of his free time in them.

Do you think this Plasma upgrade would get along with Nvidia? Learning the pros and cons of Nvidia problems with kernel upgrades has me code shy.

[Schwarzer Kater]

If your GPU does run mostly fine with Plasma 5.24 I suppose it will also run mostly fine with 5.27.

The only "real problems" I had run into with Nvidia were occasional incompatibilities with kernel updates and with Wayland - no matter which distribution.
Additional "minor annoyances" were e.g. Night Light not working automatically, sometimes Plasmoids could not read the GPU's temperature - just to name two things concerning Plasma directly as an example. But those things never were serious problems or specific to a Plasma version, more so to the Nvidia driver version IIRC - some of them came and went and came and went over the years…

That was when I still had Nvidia graphics cards in one or two of my private computers - I am glad that I solely use AMD GPUs and Intel (i)GPUs nowadays.

Unfortunately I found a "bug" today: qml-module-org-kde-notification is missing from Frameworks 5.104.
Therefore some Plasmoids that depend on it cannot be used with the Kubuntu Backports Extra PPA…

Please see below.

It has just been renamed to qml-module-org-kde-notifications

No plasmamoids in jammy archive or backports depend on the original, so I assume you mean a 3rd part plasmoid. Installing the newly named package should satisfy a plasmoids qml import dependencies.

[Schwarzer Kater]

Thank you for your correction! And sorry: stupid user error - I already had installed qml-module-org-kde-notifications in Debian 12 (Plasma 5.27.x), but somehow I forgot about the renaming…
You are right, this is used by one of my favourite third-party Plasmoids : Advanced Radio Player. Which does work now.
