Ubuntu – How to install Plasma 5.4 on Kubuntu

kubuntuplasma

Can anyone tell how to upgrade Kubuntu 15 plasma to 5.4?
I found these commands:

sudo add-apt-repository ppa:kubuntu-ppa/backports
sudo apt-get update && sudo apt-get dist-upgrade

But after restart I still have plasma 5.3. Even in Help -> About System Settings I see version 5.3.2. What else I need to do, to upgrade plasma version?

Best Answer

Use this tuto:

  1. Add Kubuntu CI Stable PPA: 

    sudo add-apt-repository ppa:kubuntu-ci/stable

    If you’ve added Kubuntu backports PPA, and it does not yet update with Plasma 5.4. You may remove it via:

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

  2. Update system cache and upgrade your system: 

    sudo apt-get update
sudo apt-get dist-upgrade

If you’re not in Kubuntu, you may run below command to install KDE:

sudo apt-get install plasma-desktop

If everything goes well, restart your computer to apply changes.
