Cloning Ubuntu 20.04 Server (Work-around found)

For some reason "sudo rpi-clone sda" from booted SDcard to USB Adapter/SDcard was not resulting in a bootable backup SDcard.

RaspberryPi 3B+
Ubuntu 20.04 64-bit Server LTS

Work-around found:

  1. Flash backup card with Ubuntu 20.04 64-bit LTS Server
  2. Boot w/o the target card inserted, then insert the target card
  3. $sudo rpi-clone sda

I ran the same command sudo ./rpi-clone sda

on a RaspberryPI 4B (4G)
running Ubuntu 20.04.3 64-Bit Server LTS

and it worked flawlessly.

Here is the log from the clone

ubuntu@ubuntu:~/rpi-clone$ sudo ./rpi-clone sda
