Hi.

I've had this for a little over a week now. I've applied several updates during that time, but this one never installs. I applied some more updates this a.m., but it is still sitting in Discover's queue. when I try to install it, it flashes a pop-up at the bottom of the screen

Code: Select all

Blocked executable in the ESP, ensure Grub and Shim are up to date: no volumes of type c12a7328-f81f-11d2-ba4b00a 0c93ec93b

I have updated both Grub and Shim using pkcon, but this "UEFI dbx" package won't install. I'm not sure what this package even is... if it is the Secureboot-dbx package, or just a revocation list... I have rebooted my PC several times...

Any ideas?

Thanks.

OK. I'm not telling anyone what to do here... but this is what I did, and it fixed it:

Code: Select all

sudo apt-get purge grub\*
sudo apt-get install grub-efi
sudo apt-get autoremove
sudo update-grub

I got this here:
