Kernel panic - system not boot after hard reboot

[Serg_500]

Hi, my proxmox version is 7.4.3.

After the server suddenly hard reboot proxmox starts with an error message:
Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

It happens when booting with kernel 5.15.104-1-pve.

I started the system with a different kernel version 5.15.30-2-pve and run update-initramfs -u -k 5.15.104-1-pve but it returned: update-initramfs: Generating /boot/initrd.img-5.15.104-1-pve E: no ldd around - install libc-bin update-initramfs: failed for /boot/initrd.img-5.15.104-1-pve with 1.

How can I fix this problem?

Any ideas?

Maybe I need to reinstall the bad kernel?

In the end, I solved the problem myself. It was necessary to reinstall the libc-bin package according to instructions. Then I run

update-initramfs -u -k 5.15.104-1-pve

and

update-grub

.
