[Bug 2150321] Re: Ubuntu 26.04 flash-kernel db is not update-to-date

[Kan Li]

Sorry for the confusion. I mixed two problems in the same ticket.

One is the flash-kernel db getting out of date, which has actually been
solved. The way it reached the problematic state was: I ran the old
tool, `update-initramfs -u -k all` which gave errors, so I ended up
installing `flash-kernel` manually.

By following your comment, I manually re-installed the Ubuntu 26.04
server on RPi4 so it is in a clean state; and I am able to run `sudo
dracut -f --regenerate-all` without an error.

The second problem is `sudo dracut -f --regenerate-all` only generates
/boot/initrd.img* but the boot process on RPi4 relies on
/boot/firmware/current/initrd.img, which is not touched by `sudo dracut
-f --regenerate-all`. Please advise how to let `dracut` correctly

Title:
  Ubuntu 26.04 flash-kernel db is not update-to-date

Status in flash-kernel package in Ubuntu:
  New

Bug description:
  I have a Raspberry Pi 4 Model B device and yesterday I installed
  Ubuntu 26.04 on it. initramfs-tools and flash-kernel packages fail to
  install (more accurately, they did get installed, but failed at
  configure step), reporting my device is not recognized. I rolled it
  back to my original Ubuntu 24.04 so I can no longer run commands to
  collect detailed information.

  By digging into it, the flash-kernel package on Ubuntu 26.04 doesn't
  ship with the latest database, while Ubuntu 24.04 does.

  The file in question is  /usr/share/flash-kernel/db/all.db, on Ubuntu
  24.04 it does contain devices Raspberry Pi 4B; on Ubuntu 26.04, it is
  still the old version.

  Please update the package on Ubuntu 26.04 otherwise I can't run
  update-initramfs properly to add LVM support in the initrd.img (I put
  the rootfs in LVM, and everything works fine for Ubuntu 24.04).
