I have the "exact" problem described here: https://askubuntu.com/questions/1432...e-uefi-dbx-217
What I am using to boot my Dell Precision 3240 is identified here:
I am not a firmware secure boot expert expert and I am not following the advice at the link except for the part that my machine might become un-bootable ...so my question is: is this something I really need to fix? or will it go away when I do a fresh install of Ubuntu 22.10 in a week or two. Also, (I am guessing here) it seems to be impacting updates because of the "security" angle (but not sure - I assume this problem if it is not related to the firmware issue will go away when I do a fresh install of 22.10 too), for exampleCode:jgw-i9@jgwi9-Precision-3240-Compact:~/Desktop$ sudo efibootmgr -v | grep "Boot$(sudo efibootmgr -v | awk '/BootCurrent/{print $2}')" [sudo] password for jgw-i9: Boot0000* ubuntu HD(1,GPT,022047eb-4164-41df-b6df-bdd2e7bc6587,0x800,0x183800)/File(\EFI\ubuntu\shimx64.efi)
