hi,

i'm a little uncomfortable with this, but I'm unable to install proxmox.

i followed https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_12_Bookworm , installed debian bookworm and rebooted without any problems.

i than configured a fixed ip-address and fixed /etc/hosts. i adapted sources.list as described, imported the repository key and verified it.
after that i executed apt update && apt full-upgrade and apt install proxmox-default-kernel followed by systemctl reboot.

unfortunately the machine does not boot - it just displays the grub-shell (GNU GRUB version 2.06-13+pmx7 ..) - pmx7 looks strange.

the odd thing is that i had previously installed proxmox on the same machine without any issues but i'm unsure if i had followed https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_12_Bookworm or another howto.

now i feel kind of lost.

thanks in advance for any hints.
 
finding: when i skip `apt full-upgrade` the machine will boot.

uname -a
Linux ms-pm07 6.8.12-15-pve #1 SMP PREEMPT_DYNAMIC PMX 6.8.12-15 (2025-09-12T11:02Z) x86_64 GNU/Linux

this makes me suspect that something is wrong with the proxmox repository.

i'm almost 100% sure that the machine will not reboot after an `apt upgrade`, `apt dist-upgrade` or `apt full-upgrade`.

What do you mean?

I use a 6 partion Setup with ZFS and 2 zfs pools with the default install proxmox ve 9 iso.
Default zfs rpool run with 2 partion boot, efi and the 3rd is the zfs poll rpool.

<ot>sorry but i do not want to discuss installation variants. i want to solve my problem - install proxmox 8.4 on debian 12.</ot>

btw.: if there is a problem with the proxmox repository what about our existing 8.4/debian 12 installations which are regularly upgraded. should i try to postpone reboots as long as possible?
 
new info: i was able to boot the machine from the grub-prompt using

grub> set
grub> insmod part_msdos
grub> insmod gzio
grub> insmod linux
grub> set root=(hd2,gpt2)
grub> linux /boot/vmlinuz-6.8.12-15-pve root=/dev/sdc2 ro
grub> initrd /boot/initrd.img-6.8.12-15-pve
grub> boot

this makes me think that the problem is in some file in /etc/grub.d .

is there anybody out there who can tell me how to fix this?
