Bug 32161

Can you please say which installation ISO you used: the Plasma Live, or Classic choosing Plasma.
And exactly what operation you were trying "lorsque l'on veut ajouter un composant graphique 'information système' sur le bureau, celà ne fonctionne pas"
That is, exactly what procedure (menu and dialogue choices) you followed. This helps to reproduce the fault.

Translated with Google :

I downloaded the iso image, Mageia-9-rc1-x86_64.iso, by installing it on a hard drive. (classic installation therefore) 

To add a graphics component: 
- Right click on the desktop - Add graphic components 
- Filter by "System Information" 
- click for example on "use of each core" or "network throughput" or "memory usage" 


The components are added to the desktop but do not work. 
When you then install Plasma-SystemMonitor and restart the computer, it's good.

(-ksystemstats-5.27.5-1.mga9.x86_64 - lib64nl-route3_200-3.7.0-1.mga9.x86_64 install with plasma-systemmonitor-5.27.5-1.mga9.x86_64)

--------------------------------------------------------
en Français : 
J'ai téléchargé l'image iso, Mageia-9-rc1-x86_64.iso,  en l'installant sur  disque dur. (installation classique donc)

Pour ajouter un composant graphique :
- Clic droit sur le bureau
- Ajouter des composant graphiques
- Filtrer par "Informations Sytème"
- cliquer par exemple sur "utilisation de chaque coeur" ou "débit du réseau" ou "utilisation de la mémoire"

Les composants sont bien ajoutés sur le bureau mais ne fonctionnent pas.

quand on installe ensuite plasma-systemmonitor et que l'on redémarre l'ordinateur, c'est bon.

(-ksystemstats-5.27.5-1.mga9.x86_64 
- lib64nl-route3_200-3.7.0-1.mga9.x86_64  s'installent avec plasma-systemmonitor-5.27.5-1.mga9.x86_64 )

Merci pur cet information.
I think I am at last with you - Plasma is not my scene.

Right-click desktop
+ Add Widgets
Near top-right of display, to the right of the search box, click 'All widgets' & select 'System Information'
I clicked on the 3 examples given. They just appeared on the desktop - and one was overlaid, so I saw just two applications. [Needed to right-click one of them, choose Edit Mode, then you can move them].

In my case, I already had installed the three pkgs cited just above,
 plasma-systemmonitor, ksystemstats, lib64nl-route3_200
so these widgets worked. But we can now see the complaint...

The requires heirarchy looks:
 plasma-systemmonitor
  ksystemstats
   lib64nl-route3_200
but is there a break?

 plasma-systemmonitor requires ksystemstats,
which is required by plasma-systemmonitor; OK

 ksystemstats is required by plasma-systemmonitor (OK);
but apparently *does not* currently require lib64nl-route3_200, which it should; ????
 $ urpmq --requires ksystemstats | grep lib64
 $
So how did installing plasma-systemmonitor pull the lib64 in (comment 0)?

 lib64nl-route3_200 is required by ksystemstats; OK

So indeed these three packages need to be in Classic Plasma; for the Live?
And the apparent dependency break ksystemstats to lib64nl-route3_200 ?

Assigning to KDE, CC'ing Martin.

After mageia installed from the ISO you have to install "task-plasma5" meta package to install some others kde/plasma components.

Present on the kde live iso, but missing from the classical installers.
