Public bug reported: I just noticed that http://archive.ubuntu.com/ubuntu/dists/focal/main/uefi/grub2-amd64/current/ includes a signed artifact I wasn't familiar with, grubnetx64-installer.efi.signed. This came in from Debian via commit e8bc4a231a2e16c25e86b7288f6de0b5a0c9bb2f:
Add an extra di-specific version of the UEFI netboot image Identical to the normal netboot image, but With a different baked-in prefix value ("$vendor-installer/$ARCH/grub" instead of "/grub"). Helps to fix #928750, making d-i consistent in terms of PXE setup. We do not need two netboot images for grub, and should definitely not be signing two of them. Please drop this artifact from the next grub2 upload. ** Affects: grub2 (Ubuntu) Importance: High Status: New ** Changed in: grub2 (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863994 Title: do not build (or sign) grubnetx64-installer.efi in Ubuntu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1863994/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
