Bug Description
i have a tablet/netbook with:
32bit UEFI (only),
SecureBoot enabled,
32/64bit CPU,
Windows 10 Pro (32bit).
i can't use the 64bit version of ubuntu 18.04.1 or 18.10 (daily-beta) to boot LiveDVD or LiveUSB,
because of missing bootia32.efi on the Live iso media.
and when i try to add the bootia32.efi by hand, then i get a signed certificate error at boot time from UEFI i guess.
why is the bootx64.efi signed properly for SecureBoot an 64bit UEFI,
but bootia32.efi isn't signed properly for SecureBoot an 32bit UEFI???
and why is that bootia32.efi missing at all on the Live iso?
i am not the only one, who is using that kind of tablet/netbook and
want to install ubuntu 18.x 64bit on that device.
i don't know if the package i told is the right one.
maybe another package is more correct...
e.g. shim-signed, grub-efi-

today i tried Fedora 29 Workstation Live (64bit).
there is a bootia32.efi that is correctly Microsoft UEFI CA signed.
with that version i can boot and use Fedora 29
on all my UEFI32 + SecureBoot enabled devices successfully.
i hope it will be fixed for Ubuntu as well soon...
