Followed this guide to setup the pxe server https://discourse.ubuntu.com/t/netbooting-the-live-server-installer-via-uefi-pxe-on-arm-aarch64-arm64-and-x86-64-amd64/19240 with the jammy beta image (220330) http://cdimage.ubuntu.com/ubuntu-server/daily-live/20220330/jammy-live-server-arm64.iso 1-1. You may use this script to perform the set-up https://github.com/tai271828/ubuntu-autoinstall-pxe-server by invoking: `sudo ./setup-pxe-server.sh --url http://cdimage.ubuntu.com/ubuntu-server/daily-live/20220330/jammy-live-server-arm64.iso` 2. Boot the system via PXE 3. Select Ubuntu at Grub menu = Expected Result = The image is loaded to the system locally via PXE, and subiquity is launched = Actual Result = Console log simply shows nothing for 10 seconds and then the kernel panic shows up. = Additional Information = - If we install via the virtual CD of the server, subiquity could be launched and the installation process completes successfully. - MAAS could deploy Jammy to the Mt. Jade server as well.
