Upgrading from Proxmox 8 to 9 issue: GRUB error: out of memory

[hanzlik]

I recommend booting from a Debian 13 Live image, but any other live Linux distribution should work just fine.

Maybe interesting. On a PBS, now running V4 ist the same hardware, same BIOS and the latest grub with no problem... Whats the difference...?

OK, works so far again. Used this howto, bec. in my case it needed to mount the lvm first.

Question is, when it is save to upgrade back to the latest grub2 ?

I‘m glad that the chroot-method worked for you
I would keep track on the Bug-Report in Bugzilla. If a new grub version is released, i‘ll test it and report back there.

I've also created a bug report - it would be great if you could comment there as well to confirm that you’re experiencing the same issue:
