no menu available after update

I can’t start menu after updating from 15.1 to 15.2

I got this error message

 Erreur du chargement du fichier QML : file:///usr/share/plasma/plasmoids/org.kde.plasma.kickoff/contents/ui/Kickoff.qml:31:1: module "org.kde.plasma.private.kicker" is not installed

any idea ?

It is hard to know what went wrong.

I did a clean install of 15.2, then restore “/home” from what it was in 15.1. And that file is here on my system.

Using Yast Software Management, I searched for “Kickoff.qml” after checking the “file list” box for the search attributes to use. And, it came up with the package “plasma5-desktop”. Is that package installed on your system? You might try:

zypper install plasma5-desktop

If you happen to have disabled following recommends, you could have ended with a very incomplete upgrade.

Hi thank’s for your answer
I did a lot of things finded on web

like sudo apt install plasma5-desktop
like zypper install …

I know if i install instead of update , i will have a clean and a desktop without problems, i did that once , but in this case i will lose all my http conf and hhtp files !! i use my PC for testing http site for some friends of my

best regards

I have install leap 15.2 without formating my partition because i did’nt want to loose teh web files and programs

after that no more problems , the menu start is avalible, all modules in yast2 running so it confirm the script update has a problem

best regards
