Plasma 5.12.5 bugfix update for Kubuntu 18.04 LTS – Testing help required

Are you using Kubuntu 18.04, our current LTS release?

We currently have the Plasma 5.12.5 LTS bugfix release available in our Updates PPA, but we would like to provide the important fixes and translations in this release to all users via updates in the main Ubuntu archive. This would also mean these updates would be provide by default with the 18.04.1 point release ISO expected in late July.

The Stable Release Update tracking bug can be found here:

A account is required to post testing feedback as bug comments.

The Plasma 5.12.5 changelog can be found at:

[Test Case]

* General tests:
– Does plasma desktop start as normal with no apparent regressions over 5.12.4?
– General workflow – testers should carry out their normal tasks, using the plasma features they normally do, and test common subsystems such as audio, settings changes, compositing, desktop affects, suspend etc.

* Specific tests:
– Check the changelog:
– Identify items with front/user facing changes capable of specific testing. e.g. “weather plasmoid fetches BBC weather data.”
– Test the ‘fixed’ functionality.

Testing involves some technical set up to do, so while you do not need to be a highly advanced K/Ubuntu user, some proficiently in apt based package management is advisable.

Details on how to enable the propose repository can be found at:

Unfortunately that page illustrates Xenial and Ubuntu Unity rather than Bionic in Kubuntu. Using Discover or Muon, use Settings > More, enter your password, and ensure that Pre-release updates (bionic-proposed) is ticked in the Updates tab.

Or from the commandline, you can modify the software sources manually by adding the following line to /etc/apt/sources.list:

deb bionic-proposed restricted main multiverse universe

It is not advisable to upgrade all available packages from proposed, as many will be unrelated to this testing and may NOT have been sufficiently verified as updates to assume safe. So the safest but a little involved method would be to use Muon (or even synaptic!) to select each upgradeable packages with a version containing 5.12.5-0ubuntu0.1 ( for plasma-discover due to an additional update).

Please report your findings on the bug report. If you need some guidance on how to structure your report, please see Testing is very important to the quality of the software Ubuntu and Kubuntu developers package and release.

We need your help to get this important bug-fix release out the door to all of our users.

Thanks! Please stop by the Kubuntu-devel IRC channel or Telegram group if you need clarification of any of the steps to follow.
