As Laszlo mentioned, this can affect other systems than QEMU. I definitely can't boot the ISO on my thinkpad when shim debugging is enabled.
Then, as discussed, fallback.efi shouldn't be on the ISO. It's clearly not going to work due to the way shim is designed. Given that, we don't need a debian-cd task to install fallback... I'm working on preparing the shim update since yesterday. I can get you a working shim if necessary for testing for a custom remastered CD image. ** Changed in: grub2 (Ubuntu) Status: New => Triaged ** Changed in: debian-cd (Ubuntu) Status: Triaged => Invalid ** Changed in: grub2 (Ubuntu) Importance: Medium => High ** Changed in: shim (Ubuntu) Status: Triaged => In Progress ** Changed in: grub2 (Ubuntu) Status: Triaged => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1624096 Title: yakkety: backport (or rebase to) fix eliminating a double-close in shim To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-cd/+bug/1624096/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
