shim is only installed on amd64

[Alfonso Sanchez-Beato]

I am installing on an arm64 server using the subiquity snap in the edge channel, version 21.04.2+git11.dabd3198, revision 2405, by using PXE boot. Kernel command line is

linux /vmlinuz console=hvc0 console=ttyAMA0 earlycon=pl011,0x01000000 fixrtc ip=:::::tmfifo_net0:dhcp url=http://192.168.100.1/tftp/bluefield.iso

The installer does not install the shim, which we would like to have for secure boot.

le sigh, curtin only installs shim-signed on amd64:

            # AMD64 has shim-signed for SecureBoot support
            if arch == "amd64":
                uefi_pkgs.append("shim-signed")

In the mean time, just adding "shim-signed" to packages in your autoinstall config should have the same effect.

Although do note that secure boot on arm64 does not actually work on all releases currently (it should start working in all releases in the next few days, though)
