Kernel panic not syncing: No working init found. (Debian sid)

On a dual-boot system: Fedora rawhide with Debian sid, the system will not boot. Fedora is operational, Debian is unable to boot. grub is being updated from within Fedora (entries refreshed properly). Kernel panic message: --------------------- Initramfs unpacking failed: ZSTD-compressed data is corrupt Failed to execute /init (error -2) CPU: 1 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.12.15-amd64 #1 Kernel panic not syncing: No working init found. Try passing init option to kernel. See Linux Documentation/admin-guide/init.rst for guidance. Things I have tried: -------------------- 1. chroot into the system from GParted Live: - chroot commands:

sudo mount /dev/sda1 /mnt
        sudo mount --bind /dev /mnt/dev
        sudo mount --bind /dev/pts /mnt/dev/pts
        sudo mount --bind /proc /mnt/proc
        sudo mount --bind /sys /mnt/sys
        sudo chroot /mnt

-

update && apt upgrade

-

--reinstall install linux-image-amd64

-

-initramfs -u -k all

2. GRUB: - Provide

=/bin/init

- Boot from command-line. 3. Lower Kernel version. 4. Documentation/admin-guide/init.rst : -

-d |grep NEEDED

is satisfied. - There was no

/bin/init

at all.
