Several Sparky Apps suddenly disappear - what is that

[Sparkyphone]

Hello,
I'm writing this, because several apps suddenly disappeared from the menu, and I have no idea, why this happened and if they are gone completely or only from the menu:
The first one was Aptus - the Sparky installation tool, gone a few months ago, okay there is Synaptic
The second one was Atril, the pdf-Viewer, I reinstalled it with Synaptic
Today I found out, simple scan is no more there, I mean in the menu
What is that ?
As I do not know what is the exact name of these apps, I cannot try to start them from the terminal
Does anybody have an idea ?
greets,
Armin

Supplement:
Together with Aptus, the update(called "upgrade")-app disappeared also. Before the update-app was displayed sometimes two times a day, or at least every three days, now nothing happenes (or perhaps I do not see it).

 Well, it seems like the first question is obvious. Which desktop (KDE, LXQt, Mate, Xfce)
 or window manager (Openbox, Fluxbox ... etc) are you using?   





Cheers !!

Hello,
desktop is Xfce, but now the situation is extrem critical. Yesterday I reinstalled another disappeared app. Today I found out that another app (I don't know the name of the app, but it is thge one like notepad) wich I really need urgently. But what is realy critical: Today the whiskermenu has disappeared. This means, I cannot use the computer in a normal way. I work hard with my computer every day. now there is no time for any reparation works anymore. I will draw the emergency break and reiinstall the whole computer with another OS - I think I will choose debian 13. What I think, there must be a real reason for such big problems, maybe a virus or something else. I never had this in the last 25 years of computing. Sorry

  I don't know what the problem you have with the menus may be.
Personally, I have checked in my XFCE installation and their menus were perfectly correct.

So, I recommend that you check out the specific XFCE forums.
Good luck !!
