Title:
  Can't upgrade kernel on Raspberry Pi

Status in flash-kernel package in Ubuntu:
  New

Bug description:
  My kid has Raspberry Pi 5 with Ubuntu. This weekend, I've updated from
  25.04 to 25.10 and 26.04. Somewhere in the way, something went wrong,
  and I'm stuck with GNU/Linux 6.17.0-1018-raspi kernel, not the latest
  7.0 that should be in 26.04.

  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

  Also know, that it is running old HDD (not SSD) from laptop, and often
  boots on the second try, with I/O errors. Don't know why, maybe just
  old HDD, maybe bad chinese SATA/USB adapter, but once it boots, it
  runs stable. But this makes the "dual reboot" kernel update
  complicated.
