Many thanks for your reply, Aruna. Is there a way to remove the installed
'5.12.0-rc3-GIDI_DEV+' kernel ? A reverse command for the 'sudo make
modules_install install' command ? I found this link which explains how to
do it manually (
https://www.cyberciti.biz/faq/debian-redhat-linux-delete-kernel-command/),
I wonder if there is a safer way.

Thanks,
Gidi
