[Bug 2003853] Re: package grub-efi-amd64-signed 1.182~22.04.1+2.06-2ubuntu10 failed to install/upgrade: installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1

[Julian Andres Klode]

Hello,

the error is:

E: Your kernels are not signed with a key known to your firmware. This
system will fail to boot in a Secure Boot environment.

You are on secure boot, but do not have signed kernels, so your system
will fail to boot. This is not a bug.
