IMO you should be running dpkg-reconfigure grub-efi-amd64-signed rather than grub-install or the grub-multi-install wrapper directly.
grub-install cannot know if there are multiple ESPs, as the ESPs are stored in debconf. This is not different from BIOS systems, where grub-install also does not do the right thing. ** 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/1876974 Title: Support multiple ESPs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1876974/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
