[Bug 2052669] [NEW] update-initramfs: Generating /boot/initrd.img-5.15.0-92-generic E: /usr/share/initramfs-tools/hooks/btrfs failed with return 1. update-initramfs: failed for /boot/initrd.img-5.15.0-92-generic with 1.

Public bug reported:

My bare metal server would not restart,

Found out that I got the following error:

    "Kernel Panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)"

I started up in a Rescue, and followed the steps in
https://askubuntu.com/a/41939/36315, to "update-initramfs -u -k
{version}".

Then I got the below message:

update-initramfs: Generating /boot/initrd.img-5.15.0-92-generic
E: /usr/share/initramfs-tools/hooks/btrfs failed with return 1.
update-initramfs: failed for /boot/initrd.img-5.15.0-92-generic with 1.

I found a workaround for it: https://askubuntu.com/a/916283/36315

   "sudo chmod -x /usr/share/initramfs-tools/hooks/fixrtc"

I did that for every file in usr/share/initramfs-tools/hooks/*

After that I did

    update-initramfs -u -k all
    update-grub

I rebooted from Rescue, and then I got the following error:

    "Kernel Panic - not syncing: No working init found. Try passing
init= option to kernel."

I reinstalled Ubuntu 22.04 on this bare metal, but even after reinstall,
I get the No working init found.

Any help is greatly appreciated!
