I'm running Kubuntu 16.04 64-bit with: KDE Plasma Version: 5.5.5; Qt Version: 5.5.1; KDE Frameworks: 5.18.0.

I attempted to get KDE 5.7 by running the following commands:

sudo add-apt-repository ppa:kubuntu-ppa/backports; sudo apt update && sudo apt full-upgrade


Reading package lists... Done

This is because KDE 5.7 hasn't been backported to Kubuntu and added to the backports ppa yet.

I've been waiting too, so I hope someone involved in the project will comment on when they expect that to be done.

Edit: I notice that you actually on KDE 5.5.5. You should at least get upgraded to 5.6.5, which is available for Kubuntu 16.04. Try running kinfocenter to double check your version information.

Update: It doesn't like like KDE Plasma 5.7 will be available for 16.04 at all, I think you will have to upgrade to 16.10 next month or switch to the Neon distribution.

  • It states that I have KDE Plasma v5.5.5 and I do install updates regularly. Aug 10, 2016 at 16:58
  • That's odd. I have 16.04 and 5.6.5. That was even before adding the backports PPA.
