How to install KDE Plasma 5.4 on Kubuntu 15.04

 

plasma 5.4

Plasma 5.4 is the last version of KDE to be released. The KDE community announced its departure a couple of days ago, and we told you about it in an article about what's new in Plasma 5.4. What the new version of Plasma brings, among other novelties, is a much improved support for high DPI values, a new full screen launcher, a new applet for sound volume, more than 1.400 icons, improved auto-complete functions, and support for searching through history.

 

With Plasma 5.4 we also have the first preview version of a session using Wayland. In systems with free graphic drivers it is possible to use Plasma with KWin, with the Wayland composer for Plasma and with the X11 window manager.

How to install or upgrade to Plasma 5.4 on Kubuntu 15.04 or 15.10

Plasma 5.4 is available through the official Kubuntu CI PPA, for both Kubuntu 15.04 and Kubuntu 15.10. To install it, open a terminal and enter the commands that we are going to give you below:

sudo add-apt-repository ppa:kubuntu-ci/stable 
sudo apt-get update
sudo apt-get dist-upgrade

If all goes well, all you have to do after this is restart the computer to apply the changes. In case something fails and you want to return to the previous state of your desktop, in a terminal enter the following commands:

sudo apt-get install ppa-purge && sudo ppa-purge ppa:kubuntu-ci/stable

With this new update we hope that many bugs have been fixed of which you informed us in our article about how to install Kubuntu 15.04, which according to what was seen in your comments were quite a few.

If you install Plasma 5.4 do not hesitate to come and leave us a comment counting your experience, and if the bugs you saw in the first instance have finally been corrected. It would be great news for all Kubuntu users, distro which unfortunately is becoming further away from Canonical.

    Does it exist for ubuntu 14.04?

      You should have no problem installing it with any other flavor of Ubuntu. Don't forget to choose the appropriate desktop before logging into the GDM.

      The best thing would be to install Kubuntu and use it by default.

    I just installed it on Kubuntu 15.04 and it works fine. In my case, 99.7 MB were downloaded and 162.3 MB were released, it means that the code has been highly refined and optimized, reducing its weight and improving performance, it shows in how fluid it works.

    Thanks for sharing the information.

    I have installed it on kubuntu 15.04 and the improvement is remarkable. Visually it improves with respect to the previous version and the consumption of resources of the cpu has decreased. In my case, a welcome update.
