I am also experiencing this error on a Raspberry Pi 4B 4Gb RAM and Ubuntu Server 20.04.02
I experienced it both with writing the image from Raspberry Pi Imager as well as writing the image in the same way as Robert did. When booting I see the same "Failed to load '//uboot/ubuntu/boot.sel'" after seeing "Found U-Boot script /boot.scr". Additionally while the Pi attempts to boot I see the following: [FAILED] Failed to start Command from Kernel Command Line. See 'systemctl status kernel-command-line.service' for details [DEPEND] Dependency failed for Command from Kernel Command Line. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1914878 Title: At boot on Pi4 with 20.04.02 i get: Failed to load '//uboot/ubuntu/boot.sel' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/u-boot/+bug/1914878/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
