Bug ID: 503855
Summary: [Plasma 6.3.4] Discover / KNewStuff repeats "cache
entry -1" and fails to apply themes properly
Classification: Applications
Product: Discover
Version: 6.3.4
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: KNewStuff Backend
Assignee: plasma-b...@kde.org
Reporter: yamehe...@tuta.io
CC: aleix...@kde.org, lei...@leinir.dk
Target Milestone: ---
System:
- KDE Plasma: 6.3.4
- KDE Frameworks: 6.1.2
- Qt: 6.8.3
- Kubuntu 25.04 (Wayland session)
- CPU: Intel Core i5-13600KF
- GPU: AMD Radeon RX 7900 XTX
Summary:
Discover and System Settings (via KNewStuff) show repeated issues when
installing global themes or color schemes from KDE Store.
Observed bugs:
- Endless repetition of "looking for cache entry / -1" messages in the console
- Themes extract multiple times, leading to warnings like "already exists"
- Discover fails to install or apply themes cleanly
- Requires manual creation of ~/.config/*.knsrc files for colors, themes, icons
- Error with transientParent: “You have not set a transientParent on
KNewStuff.Dialog...”
- Themes using legacy metadata.desktop throw warnings
Steps to reproduce:
1. Open System Settings > Appearance > Global Themes
2. Try installing themes like Sweet, Nordic, Layan, WhiteSur
3. Check logs (launch `systemsettings` or `discover` from terminal)
4. Observe the excessive output and install failures
This occurs on a clean Kubuntu 25.04 install with all Plasma 6.3.4 packages up
to date. Likely a regression in KNewStuff backend or KDE integration on
Discover.
Thanks in advance for your help!
