Kubuntu 21.04 was released in April 2021 and it ships with the KDE Plasma 5.21 desktop environment series by default. As expected, those who have installed the Ubuntu flavor on their PCs would want to upgrade to the recently release KDE Plasma 5.22 desktop environment series, and now they can. The Kubuntu team announced today that the KDE Plasma 5.22 packages are now available in the Kubuntu Backports PPA repository, along with newer versions of the KDE Frameworks and KDE Gear software suites, and you can enjoy them all if you follow the next instructions.
