SOFTWARE/OS VERSIONS
Operating System: CachyOS Linux
KDE Plasma Version: 6.5.1
KDE Frameworks Version: 6.19.0
Qt Version: 6.10.0
Kernel Version: 6.17.5-2-cachyos (64-bit)
Graphics Platform: Wayland

Localization: Swedish / Sweden

ADDITIONAL INFORMATION
Sys log spits out the following:

2025-10-31 09:28    plasmashell    Failed to find plasmoid path for "org.kde.plasma.weather"
2025-10-31 09:28    plasmashell    --------> load applet: "org.kde.plasma.weather" relpath: "plasma/plasmoids/org.kde.plasma.weather"
2025-10-31 09:28    plasmashell    .. pathes: QList()

Which seems to indicate the built-in widget is still trying to look at the old path instead of the new (compiled) library in /usr/lib/qt6/plugins/plasma/applets

This does not seem to occur for every CachyOS user, but I have not done anything in particular to my KDE installation more than pacman -Syu to keep it updated.
Comment 1 Nicolas Fella 2025-10-31 13:05:57 UTC 
It seems to work when dragging the applet onto the desktop, but not when just clicking on it

Wow, you're correct. That hadn't occurred to me to try. Thanks for the work-around if nothing else! :)

Fix WidgetExplorer::addApplet

Looking up the package directory won't work for applets that use plasma_add_applet

It's also entirely unnecessary since we can and should just pass the applet id to createApplet
