These release notes for Kubuntu 17.04 (Zesty Zapus) provide an overview of the release and document the known issues with Kubuntu 17.04.

Support lifespan

Kubuntu 17.04 will be supported for 9 months.

Plasma 5.9 - Designed to be a Breeze, Plasma 5 is simple by default, powerful when needed


Plasma 5, the new generation of KDE's desktop has been developed to make it smoother to use while retaining the familiar setup.

Version 5.9 - the ninth set of updates to Plasma 5 is the default in this release of Kubuntu.

Folder view is now the default setting for the Plasma Desktop for new installations and new user accounts.

KDE Applications 16.12.3


Kubuntu comes with KDE Applications 16.12.3 containing all your favourite apps from KDE, with the exception of PIM and related products.

This is the 16.12.3 update with bugfixes and translation updates. Most applications have been ported to KDE Frameworks 5 but those which aren't should fit in seamlessly.

KDE PIM applications have been held at version 16.04.3 as 16.12.3 packages did not quite make it for release day. Packages for 16.12.3 are now available in backports PPAs. Details can be found later in these release notes.

Non-KDE applications include LibreOffice 5.3.1 and Firefox 52.0.1.

Other release highlights

  • KDE Frameworks 5.31
  • Calligra Office Suite updated to Qt/KF5 version 3.0.1
  • Krita latest bugfix release - after this popular and advanced digital painting application was split from Calligra.
  • K3B updated to a Qt5/KF5 preview snapshot of the upcoming release from KDE Applications 17.04.
  • Okular PDF and document reader is now Qt/KF5 in applications 16.12
  • Kdevelop is now the most recent bugfix release of the 5.0.x series.
  • Numerous application and translation updates from KDE.

Getting Kubuntu 17.04

Upgrading from 16.10

Download a Disk Image

Note: It is advisable to purge the backports PPA (if enabled) before attempting an upgrade. To do that run in a terminal:

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

To upgrade to Kubuntu 17.04 from 16.10:

- Open Discover or optionally Muon Package Manager
- Ensure that your current system is up to date by installing available updates

If for some reason Discover does not then offer you the upgrade to 17.04, but you know it is available, you can do one of the following:

- Launch the graphical release upgrade by opening Krunner, or Konsole (or other terminal), and run:

kdesudo do-release-upgrade -m desktop -f DistUpgradeViewKDE

- Search for and run update-manager from the K menu or Krunner if you have this installed.

- Or if you want to upgrade purely via the console, run do-release-upgrade at your prompt.

- Download a Bootable image. Direct downloads, torrents, and zysnc are available as options.
- The following link contains some tips to put the image onto a DVD or USB Drive

Getting KDE PIM 16.12.3 packages from backports PPAs

We missed by a whisker getting updated PIM 16.12.3 (kontact, kmail, akregator, kgpg etc..) into Zesty for release day, and we believe it is important that our users have access to this significant update.

Therefore packages for PIM 16.12.3 release are now available in the Kubuntu backports PPAs.

Instructions for installing and installation options can be found in the announcement on our main webiste:

KDE PIM update now available for Zesty Zapus 17.04
