This is presumably because you are on a system using UEFI with
SecureBoot, and therefore the loading of external grub modules fails
('insmod udf'), and we do not build udf support into the signed UEFI
GRUB image.Because the UEFI GRUB image is signed into the SecureBoot regime as trusted code, the standards for security are higher, and we would no simply enable an additional filesystem driver without some measure of security review. ** Package changed: syslinux (Ubuntu) => grub2 (Ubuntu) ** Changed in: grub2 (Ubuntu) Importance: Undecided => Wishlist -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1820222 Title: Unable to boot LiveCD ISO from UDF filesystem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1820222/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
