[Bug 1841955] Re: Can't upgrade kernel on raspberry pi3a+

[Launchpad Bug Tracker]

This bug was fixed in the package flash-kernel - 3.98ubuntu11~18.04.1

---------------
flash-kernel (3.98ubuntu11~18.04.1) bionic; urgency=medium

  * Permit flash-kernel to workaround an inconsistent /boot directory when
    triggered prior to the kernel finishing its triggers (LP: #1861292)

flash-kernel (3.98ubuntu10~18.04.1) bionic; urgency=medium

  * SRU of 3.98ubuntu10 to support Raspberry Pi 4B. (LP: #1847587)
  * Removed new entries from db/all.db for machines that were not already
    supported on Bionic
  * Remove "quiet splash" from kernel command line options; Bionic shipped
    without these options and we shouldn't change the boot experience for
    existing users
  * Ensure the "overlays" dir always exists on the boot partition; the Bionic
    image for the Pi 2 shipped without this dir

Bug description:
  [Impact]

  Can't upgrade kernel on raspberry pi3a+. Without this, users can be
  stuck with old kernels.

  [Test Case]

  1. dd the image in an SD card:
     http://cdimage.ubuntu.com/ubuntu/releases/18.04/release/ubuntu-18.04.3-preinstalled-server-armhf+raspi3.img.xz
  2. Boot rpi3a+ with the sd card
  3. Upgrade the kernel using following command:
     sudo apt update
     sudo apt install linux-raspi2
  4. Check output message

  Expected Result
  Current stable kernel(4.15.0-1043-raspi2) is installed.

  Actual Result
  Error shows up during the installation, and the kernel is still the original one after reboot.

  [Regression Potential]

  None. The bugfix for this change is only adding the missing db/all.db
  Pi3A+ entry to flash-kernel.
