[kde-unstable] Missing default Breeze/Breeze Dark styles

This post is continued from an upstream KDE bug report: https://bugs.kde.org/show_bug.cgi?id=478020

I was having an issue regarding Plasma's OSD not showing after upgrading to Beta 1 from KDE 5, and this turned out to be a theming problem. I was told to switch to the Breeze global theme as a troubleshooting step and while this *did* fix the issue, it caused Plasma's styling to disappear and just generally look broken:

Upon further investigation it seems that for some reason Plasma isn't detecting Breeze's "Plasma Style". Looking in System Settings shows after selecting Breeze as a global theme reveals that no Plasma Style is selected. Setting one from a custom theme causes this problem (and curiously, my original OSD issue) to be fixed, but it's definitely not a permanent solution:

It was determined in the thread that this is likely a downstream packaging issue with Arch, so here I am to bring this issue to this forum. How should I proceed from here?

Could you provide a list of installed packages and their versions?

pacman -Q

In particular, did you install breeze, breeze-gtk, and breeze-icons? And maybe try reinstalling them to see if it helps.

Sure. I put it on Pastebin since it's a long list. https://pastebin.com/DRS5jVjE

Re: [kde-unstable] Missing default Breeze/Breeze Dark styles

breeze 5.90.0-1
breeze-gtk 5.90.0-1
breeze-icons 5.246.0-1
breeze5 5.90.0-1

breeze5 doesn't seem to be required by anything [1], so maybe it should be removed?

Re: [kde-unstable] Missing default Breeze/Breeze Dark styles

Removed breeze5, reinstalled breeze, breeze-gtk, and breeze-icons and I still appear to be missing the global theme.

I do have a theory from looking at the logs, though. So, I set my global theme to Breeze and ran plasmashell --replace to clear everything out. At startup, I see this:

$ plasmashell --replace
Qt: Session management error: Could not open network socket
kf.plasma.core: Could not locate metadata for theme "default"

Later in the log, one of my installed plasmoids happens to log the theme path being used to stdout:

Window Buttons : current plasma theme :::  ""
Window Buttons : theme path :::  "/home/jvyden/.local/share/plasma/desktoptheme/"
Window Buttons : theme widgets path :::  "/usr/share/plasma/desktoptheme/default/widgets"
Window Buttons : plasma theme original colors :::  "/usr/share/color-schemes/BreezeLight.colors"
Window Buttons : plasma theme default colors :::  "/tmp/plasmashell-WTFlUj/default.colors"
Plugin changed to:  "org.kde.breeze"
Searching for plugins:  "org.kde.breeze"

I don't have a "default" folder in my local theme folder, so I copied it over from /usr/share/plasma/desktoptheme to my local user folder but still no dice. I wonder if something about the default theme is causing it to be unloadable?

Re: [kde-unstable] Missing default Breeze/Breeze Dark styles

Do the themes appear if you create a new user with a clean .config folder?

They do not. Colors appear as expected, but many of the same styling/layout issues appear again. So we can rule out my configuration, it seems:

What do you see for

 ls -al /usr/share/plasma/desktoptheme/

Apologies for the delay. Here's the output of that command:

$ ls -al /usr/share/plasma/desktoptheme/

Re: [kde-unstable] Missing default Breeze/Breeze Dark styles

I have the same issue, i ave the same output for usr/share/plasma/desktoptheme/ , however i noticed that both breeze-dark and breeze-light are empty folders, and only the ones in ~/.local/share/plasma/desktoptheme/ show up.

Re: [kde-unstable] Missing default Breeze/Breeze Dark styles

both breeze-dark and breeze-light are empty folders

You can try reinstalling those packages, but chances are that you have a dying disk.

Re: [kde-unstable] Missing default Breeze/Breeze Dark styles

I happen to face the same issue when :
- Enabling the KDE-unstable repository
- pacman -Syu

A fresh install of Arch in a virtual machine doesn't seem to be affected.

If someone has some indication on how to debug this I will happily provide more feedback.

Re: [kde-unstable] Missing default Breeze/Breeze Dark styles

I found a fix for this.

During the update to Plasma 6, don't replace oxygen and breeze packages by oxygen5 and breeze5.

Re: [kde-unstable] Missing default Breeze/Breeze Dark styles

Found another fix that resolves it for users who already "wrongly" installed Plasma 6.

You need to reinstall libplasma.
