Kubuntu 24.04 to 24.10 Upgrade: module "org.kde.plasma.components" 2.0 not installed

[archibald-sassafrassalad]

Upon upgrading to 24.10 from 24.04.1, I receive the error

file:///home/archibald/.local/share/plasma/plasmoids/org.kde.desktopcontainment/contents/ui/main.qml:14:1: module "org.kde.plasma.components" version 2.0 is not installed

when signing in to my desktop. My desktop doesn't show anything apart from that error and many of the buttons on the dock are missing. I noticed this might be due to a theme issue, so I tried switching between Breeze and the default Kubuntu theme, but received the same error in both.

Never mind, this is an error with my configuration.

Hello, I got the same error, but at different place - I upgraded from 24.04 to 24.10 (thus Plasma 5 to Plasma 6), and when I install new plasma widget, I got exactly that error:

~/.local/share/plasma/plasmoids/com.github.zren.commandoutput/contents/ui/main.qml:5:1: module "org.kde.plasma.components" version 2.0 is not installed

I tried to uninstall the widget, then remove the dir in plasmoids, then install again, but still getting the same error.
Can anyone help please?

Are you sure you installed the plasma6 version of the applet: https://store.kde.org/p/2136636/ (probably not)

[MikeDef]

Yes, I installed v14 (for the plasma 6). I even tried it both ways - install using local file and install directly from the widget menu.
(There was version for plasma 5 just after the update from 24.04 to 24.10, and there was an error saying it is a widget for older unknown version of plasma. So I uninstalled it and installed version for Plasma 6. Since then I have the error described above.)

I don't know what widget would be creating the directory ~/.local/share/plasma/plasmoids/org.kde.desktopcontainment/ , the name doesn't make sense for user-installed widgets. I suggest (re)moving that to some other location temporarily and seeing if that clears things up.

Can you post the contents of the file ~/.local/share/plasma/plasmoids/com.github.zren.commandoutput/contents/ui/main.qml (only the 'import' rows should be enough)

import QtQuick
import QtQuick.Layouts

import org.kde.kirigami as Kirigami
import org.kde.plasma.plasmoid
import org.kde.plasma.core as PlasmaCore
import org.kde.plasma.components as PlasmaComponent
import org.kde.plasma.plasma5support as Plasma5Support

These imports work fine on my end (I'm on Neon, though), the org.kde.plasma.components import loads version 3.0 (which is installed), not version 2.0 that your import's try to load (judging by the error message)

This doesn't work for me, as I mentioned above.

Here it is:

import QtQuick
import QtQuick.Layouts

import org.kde.kirigami as Kirigami
import org.kde.plasma.plasmoid
import org.kde.plasma.core as PlasmaCore
import org.kde.plasma.components as PlasmaComponent
import org.kde.plasma.plasma5support as Plasma5Support​

It looks exactly the same as yours.
