Comment 21 for bug 1711203

To be clear, although installing the signed kernel package is necessary, a failure to do this is NOT the source of this bug, which seems to relate to how Shim and/or GRUB handle the MAAS boot path, which involves Shim and GRUB being PXE-booted and then chainloaded to (Shim and?) GRUB on the hard disk. I am available for testing of proposed fixes; I have one system with Secure Boot available on my home network and sporadic access to others in 1SS (from OIL; we can transfer them over to the certification network from time to time).
