Ubuntu 20.04 LTS

• USB only
  • https://www.raspberrypi.org/forums/viewtopic.php?f=131&t=278791
  • https://jamesachambers.com/raspberry-pi-4-ubuntu-20-04-usb-mass-storage-boot-guide/ (more info)
• MicroSD/USB boot:
  • https://askubuntu.com/questions/1254810/booting-ubuntu-server-20-04-on-pi-4-from-usb.
  • TLDR: Rename (from writable) or remove the 2nd partition on MicroSD card so the one on the USB drive is used during boot. WARNING: Remove/rename the LABEL=system-boot partition from the SSD so /boot is mounted from the MicroSD (this step is listed as optional but its not!)
    • Once the SSD boot partition is renamed/removed, see Missing linux modules on https://github.com/hrpatel/raspberry-pi/wiki/k3s-Installation to fix the modules permanently
• Container support
  • https://askubuntu.com/questions/1189480/raspberry-pi-4-ubuntu-19-10-cannot-enable-cgroup-memory-at-boostrap

Procedure

• Set hostname
• Enable container support
• Fix linux modules [optional] (if you forgot to remove boot partition from the SSD like I did)
