Kollision for Upgrade of breeze in OpenMandriva ROME

So my guess is that your system is a mix of plasma5 and plasma6 packages breaking plasma. There are a couple of ways to fix this.

  1. You could try

dnf install task-plasma6

and see all the conflicts. Then run the dnf swap command like before on each of the conflicts listed. I would then run

dnf install task-plasma6

again. Repeat if there are more conflicts.

  1. You could run

rpm -qa |grep 5.27.11

To get a list of plasma5 packages installed. Remove all these packages and then run

dnf install task-plasma6

NOTE: I would do all of this from a virtual console and not the GUI.

Here is a link to what I had to do.
