Installing KDE Plasma 5.22 in Ubuntu 21.04

If you are running GNOME based default Ubuntu 21.04 Hirsute Hippo desktop, you can use this PPA to install the latest KDE Plasma. Here’s how.

Open a terminal and add the PPA (like above steps).

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

Then, refresh the packages.

sudo apt update

Then run the below to install the Kubuntu desktop.

sudo apt install kubuntu-desktop

This will install the KDE Plasma desktop alongside with GNOME in Ubuntu 21.04.

KDE Plasma 5.22 in Ubuntu 20.04 LTS

Ubuntu 20.04 LTS edition has the earlier KDE Plasma 5.18, KDE Framework 5.68, KDE Applications 19.12.3. So, during its entire lifecycle, it would not receive the latest KDE Update. So, technically you can add the above PPA and install the KDE Plasma 5.22. But I would not recommend it due to incompatible packages, frameworks that may lead to an unstable system.

So, it is recommended that you use either Kubuntu 21.04 with the above backports PPA Or, use KDE neon to experience the latest Plasma desktop.

Uninstallation of KDE Plasma 5.22

If you change your mind and want to go back to the stock version of the KDE Plasma, then install the ppa-purge and purge the PPA. This will downgrade packages and make the stock version available.

sudo apt install ppa-purge
sudo ppa-purge ppa:kubuntu-ppa/backports
sudo apt update

Closing Notes

I hope this quick guide helped you to install the latest KDE Plasma 5.22 in Kubuntu 21.04 Hirsute Hippo. This allows you experience the latest KDE technology coupled with KDE Framework and applications. However, you should be aware that not all the features should be made available in the backports PPA – only the selected features and bug fixes that pass regression and safe to use. That said, you can always install KDE Neon as a fresh system to enjoy the latest tech from KDE.
