KDE Plasma 5.16

KDE Plasma desktop 5.17 was released yesterday. Now you can install it in (K)Ubuntu 19.10 via KUbuntu Backports PPA.

Plasma 5.17 release highlights:

  • Night Color for X11.
  • Fractional scaling support on Wayland.
  • Faster startup performance.
  • New panel in System Settings for configuring Thunderbolt devices
  • Improved widget resizing, settings panels, and many other small feature additions.
  • For more details, see the release note.

How to Install Plasma 5.17 in (K)Ubuntu 19.10:

Open terminal either via Ctrl+Alt+T keyboard shortcut or by searching for ‘terminal’ from application menu. When it opens, do:

1. Add Kubuntu Backports PPA:

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

Type user password (no asterisk feedback) when it prompts and hit Enter to continue.

2. Install Plasma 5.17 in Kubuntu 19.10:

Either install all system update via Update Manager, or run command in terminal:

sudo apt update && sudo apt full-upgrade

3. For non-Kubuntu user:

Run command to install Plasma desktop:

sudo apt update && sudo apt install plasma-desktop

or install full KDE desktop environment via command:

sudo apt update && sudo apt install kubuntu-desktop


You can purge the Kubuntu Backports PPA, which also downgrade Plasma desktop to the stock version (5.16.5) in Ubuntu 19.10 repository.

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

  1. Thank you for the help!

  2. Can not update to 5.15.17
    For some reason after adding ppa:kubuntu-ppa/backports (I’m on Kubuntu 19.10)
    it only upgrades to 5.16.5

    And list command bellow shows that latest available version is 5.16.5
    $ sudo apt list plasma-desktop
    Listing… Done
    plasma-desktop/disco 4:5.16.5-0ubuntu1~ubuntu19.04~ppa1 amd64 [upgradable from: 4:5.15.4-0ubuntu1]
    plasma-desktop/disco 4:5.16.5-0ubuntu1~ubuntu19.04~ppa1 i386

    What’s wrong?

  3. I have installed Ubuntu 19.10 along with Plasma 5.17.1 (from Kubuntu ppa backports).

    Now i want to upgrade to Plasma 5.17.2, do i use the same command as Kubuntu :
    sudo apt update && sudo apt full-upgrade ?
