Title:
  Raspberry Pi new boot asset failed

Status in flash-kernel package in Ubuntu:
  Confirmed

Bug description:
  After updating the kernel for raspberry pi 4 with Ubuntu 25.10 I get
  the following error:

  piboot-try:
  New boot assets in /boot/firmware/new failed. Fallen back to known good
  state. Use piboot-try --reset-new to re-test boot assets. If you are able
  to determine the boot failure is due to a bug, please file an issue:
  ubuntu-bug flash-kernel

  GNU/Linux 6.17.0-1003-raspi aarch64 is the running kernel.

  I tried to upgrade to: GNU/Linux 6.17.0-1004-raspi

  I also tried to deinstall an reinstall the kernel, but that didn‘t
  work. I also got the error when I first installed the OS with the
  raspberry pi imager
