Hi,
Thanks to those who responded! Sam, Dan, Adam, Sergio...
The problem has been resolved. I removed all but the kernel-headers package and paused there to run vboxconfig. I got lucky so I stopped... Otherwise I would have done the suggested "dnf distro-sync kernel-headers" command.
I experienced other problems during this "project", namely the command line length problem in the grub menu entry (extensive cursor movement caused an apparent system freeze). Should I write this up?
I also have been having trouble booting with the 5.19 kernels. After the dracut-post processing, something runs through devices by UUID but NEVER completes so... NO BOOT. Should I write this up?
Otherwise, things are GREAT here (at the moment anyway)... SO. THANKS AGAIN FOR THE HELP!!!
Best regards and STAY SAFE!
George...
