The latest KDE Plasma Desktop 5.8.5 was finally made into Kubuntu Backports PPA several hours ago, available for Ubuntu 16.04, Ubuntu 16.10 and derivatives.

Plasma 5.8.5 is a bug-fix release for the 5.8 LTS series that features:

  • Notice when the only screen changes.
  • Revert ‘Do not ask for root permissions when it’s unnecessary’, it caused problems with adding a new user.
  • Fix compilation with Qt 5.8.
  • See the full changelog of Plasma 5.8.5.

How to Install / Upgrade to Plasma 5.8.5 in Ubuntu:

For non-KDE users, you may first search for and install the kubuntu-desktop package via Synaptic Package Manager, or using the apt install command before starting following steps.

1. Open terminal emulator from App Launcher and run command:

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

Type in password when it prompts and hit Enter.


2. Then a full system upgrade will bring the current Plasma desktop to the latest (need restart):

sudo apt update

sudo apt full-upgrade

How to restore:

To undo the installation and restore to the stock version of Plasma desktop in Ubuntu 16.04/16.10, run command to purge the PPA repository:

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

The commands will remove the PPA and downgrade all installed packages from that repository to the original versions.
