[Bug 1955353] Re: Installing linux-modules-extra-raspi in chroot triggers flash-kernel which fails

[guysoft]

Hey, so tested, adding Raspberry Pi 4 Model B" to /etc/flash-kernel/machine makes the dpkg install not crash.
However the modules on docker don't work until I run:


$ sudo dpkg-reconfigure flash-kernel

On the physical device after the .img has been flashed to it.

Which means it needs to flash something.

  Its not possible install linux-modules-extra-raspi in chroot, because it activates flash-kernel which fails.
  I also tried to bypass flash-kernel by moving /sbin/flash-kernel aside before installing, but then the issue of docker failing does not get fixed.

  This means that a number of distros I maintain can't have docker
  running correctly.

  Things I tried:

  Patching as describe here: https://forums.raspberrypi.com/viewtopic.php?t=258056
  Then moving before install /sbin/flash-kernel to /sbin/flash-kernel.bak

  Results in the following output:
