Proxmox VE 6 to 7 upgrade trouble...

Hello friends,

I am new to Proxmox, of which I heard very good reports.

I have a dedicated server at Soyoustart/OVH, which has a ready made template with Debian 10 and Proxmox VE 6.

When I run the upgrade from VE 6 to VE 7 as explained here

https://pve.proxmox.com/wiki/Upgrade_from_6.x_to_7.0

upon reboot my server refuses to boot... :(

I have no idea if before rebooting perhaps I am supposed to modify any grub entry... but it appears that the upgrade changes something for which my server cannot boot anymore.

Should I be stuck with using VE 6 (not really ideal), would not running apt-get dist-upgrade manually protect me from the system updating automatically?

I would appreciate it loads if you could please answer the question above and help me to troubleshoot this issue.

Many thanks!

I had this problem with an OVH server. Luckily it has IPMI access so I changed the boot order to skip the issue I had https://forum.proxmox.com/threads/grub_is_lockdown-after-upgrade-to-7.96819/

Someone else told me they done the following via rescue mode "I booted in rescue @ ovh, reinstalled grub to the main disk, fiddled with efimgr… and it finally worked…"

Let us know what you do if you fix this, seems to be a common issue with OVH/SYS/Kimsufi

Thanks so much for your reply @harmonyp !!! I will definitely look into it.

I'm pleased that there is a solution. I'm not too familiar with fiddling with rescue at OVH (last time I tried it was refusing to mount any of the partitions as they are "Linux RAID" and not Linux Filesystem).

I'll speak to my system analyst to ensure that we can tackle this and fix it, and, as you request, I will update this same thread.

@harmonyp I'm finding it a bit confusing to tackle this. As you said, I would like to share with the forum users what is done eventually to fix my issue.

Would you mind, please, sharing the exact steps you took to fix it in your case via IPMI?

Many thanks!

I just set up another node and it worked fine now. The only thing I did different was installed console-setup (apt install console-setup) and afterwards ran

Code:
update-grub
update-initramfs -u -k all

Maybe you can try do that in chroot

Can't remember exactly what I done in but I went into BIOS and changed whatever was the 2nd boot order to first. I think it was to skip network something.

I'm not using OVH but while upgrading PVE6.4 to 7.0 and debian 10 to 11 the apt dist-upgrade updated grub-pc and wanted to write the new bootloader to my boot disks. But the new grub version wasn't able to recognize my old grub partition. I needed to remove the "boot" flag and add the "bios_grub" flag to my old 1 MB grub partition (sda1) using...
Code:
parted /dev/sda
set 1 boot off
set 1 bios_grub on
q
update-grub
...or otherwise update-grub failed with this error:
Code:
grub-install.real: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.
grub-install.real: error: embedding is not possible, but this is required for RAID and LVM install.
