Ubuntu 18.04.6 refreshed the disc images for the amd64 and arm64 architecture, re-enabling the usage on Secure Boot enabled systems due to the key revocation related to the BootHole vulnerability.

In August 2020, a set of security vulnerabilities in GRUB2 (the GRand Unified Bootloader version 2) collectively known as BootHole were disclosed. Today, another set of vulnerabilities in GRUB2 were disclosed, with similar implications.
