Comment # 13 on bug 1221515 from Olivier Belleux

Hello, 

I've retried to upgrade to "KDE 6". I still had two problems but I was able to
identify the cause; it was the Haruna package. After uninstalling it 
```sudo zypper -v dup -D --allow-vendor-change``` no longer returns any
problems.

So I logged into tty and did:
– sudo zypper -v dup --allow-vendor-change
– sudo zypper -v install pattern:kde_plasma6
– reboot

Unfortunately SDDM loaded without themes and complained about not finding some
files.
I was able to resolve these errors by mannualy installing:
– libQt6QuickLayouts6
– libQt6Xml6
– libQt6Svg6

These three packages seem necessary for SDDM to load the breeze-openSUSE theme
but they are not listed as dependencies.

After that the theme loaded but I couldn't connect. I think the problem is with
breeze-openSUSE.

So snapper rollback and back to KDE 5 for now. My first attempt went pretty
well even though it turned out to be unsuccessful.

At the moment I'm looking for the cause and solution to this SDDM malfunction
which is preventing me from logging in.

As far as I can tell, this bug seems almost solved except for the three Qt6
packages that are not istalled by default

Thank you for your efforts to package "KDE 6" and have a good evening.
