With your help I now see that my son's system has the same
virtualbox.desktop file that's on the other systems:

rocky ~ # cat /usr/share/applications/virtualbox.desktop
[Desktop Entry]
Name=Oracle xVM VirtualBox
Type=Application
Comment=Run several virtual systems on a single host computer
Exec=VirtualBox
TryExec=VirtualBox
Icon=virtualbox
Categories=System;Emulator;
rocky ~ #

As a layman it's not clear to me whether the
"Categories=System;Emulator;" say put this in System, or put it in
System->Emulator but it's not anywhere I can find so it appears that
the install 'failed to trigger the update mechanism'.

Unfortunately when I attempt this it fails as it appears the document
it's trying to load is empty/corrupted

mark@rocky ~ $ kbuildsycoca4 --noincremental
kbuildsycoca4 running...
kbuildsycoca4(3126) VFolderMenu::loadDoc: Parse error in
"/home/mark/.config/menus/applications-merged/xdg-desktop-menu-dummy.menu"
, line  1 , col  1 :  "unexpected end of file"
kbuildsycoca4(3126) KConfigGroup::readXdgListEntry: List entry
text/html in "/home/mark/.local/share/applications/mimeapps.list" is
not compliant with XDG standard (missing trailing semicolon).
mark@rocky ~ $ cat
/home/mark/.config/menus/applications-merged/xdg-desktop-menu-dummy.menu
mark@rocky ~ $

Now, as a second test I logged in as my son and looked in his menus.
The icon isn't there but in his account the kbuildsycoco4 command
didn't fail, but it also didn't appear to create the icon:

matt@rocky ~ $ kbuildsycoca4 --noincremental
kbuildsycoca4 running...
matt@rocky ~ $

To verify this is there a file in my account that holds the icon info
that I can look at? (Not edit, just look at.)

Anyway, it's still apparently not working.

Thanks,
Mark
