The MAAS environment I've been using to reproduce this is virtual. I have MAAS running in an LXD container connected to an LXD Pod. To recreate this environment you'll have to install MAAS 2.8, python-pylxd from github(if using the Debian packages), and apply this[1] patch to reenable secure boot. After MAAS is setup you'll need to configure LXD to accept remote connections to be able to add it as a MAAS Pod.
This bug should be reproducible using LXD 1. Download GRUB and the shim. MAAS gets both from Bionic, you can download them direct here[1] 2. Setup a TFTP server to provide them 3. Add grub.cfg from MAAS[3] 4. Setup DHCP - Example dhcpd.conf from MAAS[4] 5. Create LXD VM 6. Modify LXD VM to boot from over the network 7.
