How to install Plasma 5.4 on Kubuntu

Question

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?

Solution

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.
