Mantic will EOL soon. This has never been supported in noble. It's unfortunate that it remained enabled in mantic as long as it did when we knew we intended not to support it, inducing some users to rely on an unsupported configuration, but I don't think there's any more action to take here.
If you don't care about the integrity of SecureBoot, you can disable it in your firmware. Or you can locally sign a grub.efi including whatever modules you want. But for the EFI binary signed by Ubuntu, we have a duty to ensure the code doesn't unduly risk the security of all Ubuntu users, and the luks2 module has not passed muster. ** Changed in: grub2 (Ubuntu) Status: Fix Released => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1999345 Title: please add luks2 module to the signed grub2 images To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1999345/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
