I've used efibootmgr with --disable-verification. Now I get two messages : insecure mode System reset and then it reboots ...
efibootmgr -v had many (over 30) ubuntu entries, might be created during attempts to re-install ubuntu 22.04. I've removed all the duplicate entries.
Existing ubuntu entry has correct disk UUID and path pointing to shim file on EFI partition under ubuntu folder.
