My Klipper is setted to keep only one entry in history. Sometimes when I copy some text, the moment I try to paste it, the system does not paste anything. If I go to Klipper applet, I don't see anything in the current history entry
If you only want one entry, just disable klipper.
I rephrase the message. Sometimes the copy and paste does not work. I copy some text, and when I try to paste it, the system does not do anything. Since Klipper should be the manager of all copy and paste actions in Plasma, when the problem occurs, I go to Klipper to check out what he memorized, and it has nothing in the "paste slot" that should be active
I also saw this a few times. It's happening very rarely and I cannot relate it to any action for the time being. I have 10 entries in klipper (more one some PCs), and sometimes I find myself pasting nothing, looking at the entry list the last is empty, even though I'm fairly sure I didn't copied something empty. This is very hard to reproduce for me so... feel free to take this with a grain of salt
You misunderstood the functionality of klipper. It is not the clipboard, but just the history. Clipboard is handled by the windowing system (e.g X11). If the clipboard is empty it's not klipper's fault.

The fault is most likely with the application. I try to explain how a clipboard works: * application A takes the clipboard and provides content * application B takes the content This uses X11 functionality, but it's not like X11 as the server provides the clipboard. It's just a shared medium between all applications. If it doesn't work it's mostly the fault of the application in question.
I want to share the following information, it may be useful to other people: I have found out what interfered with the copy and paste action: a virt-manager session running Fedora LXQT. Everytime it runs, the problem happens

For information completeness, it looks like a Spice problem https://gitlab.freedesktop.org/spice/spice-gtk/issues/36#note_44581
