Bug ID: 466765
Summary: with 5.27.2 discover home tab never loads at startup
or when selected
Classification: Applications
Product: Discover
Version: 5.27.2
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: discover
Assignee: plasma-b...@kde.org
Reporter: rikmi...@kde.org
CC: aleix...@kde.org
Target Milestone: ---
SUMMARY
In Kubuntu and Lubuntu/UbuntuStudio 23.04 (which both ship discover), 5.27.2
discover 'home' tab never loads at startup, or when re-selected after viewing
another tab.
Additionally, while discover is both the foreground application and the home
tab is active, discover process uses a high cpu load. Selecting another tab or
another app as foreground cuts off the usage.
Downstream bug:
https://bugs.launchpad.net/ubuntu/+source/plasma-discover/+bug/2008968
STEPS TO REPRODUCE
1. Run the daily live 23.04 ISO from
http://cdimage.ubuntu.com/kubuntu/daily-live/current/ and start discover; or
2. Install discover 5.27.2 on 22.10 via ppa:kubuntu-ppa/backports
SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.27.2
KDE Frameworks Version: 5.103.0
Qt Version: 5.15.8
Packagekit: 1.2.6-3 (direct sync from debian testing/unstable)
ADDITIONAL INFORMATION
Appears to be a regression introduced by commit
https://invent.kde.org/plasma/discover/-/commit/5dadd14ff12b8a6afae2c557d5948c5c66e1898c
This was confirmed by git bisect of the changes in 5.27.2 since 5.27.1, and
confirmed by test adding a patch reverting that commit to our packaging.
Konsole output after several launches:
lunar@lunar:~$ plasma-discover
fetch ratings! false
adding empty sources model QStandardItemModel(0x56409f738490)
no component found for "com.ubuntu.ubuntu"
packagekitqt.transaction: Unknown Transaction property: "Sender"

packagekitqt.transaction: Unknown Transaction property: "Sender"
QVariant(QString, ":1.94")
packagekitqt.transaction: Unknown Transaction property: "Sender"
QVariant(QString, ":1.94")
which does not differ from 5.27.1 or the reverted state as far as I can see.
Though there is some variation on output from testers.
