Proxmox Installer Rescue Boot: unknown algorithm 68

[Andreas_H]

Hello,

I made a fresh install of Proxmox using the current ISO (7.1-2). I used ZFS (RAID 1) with two disks.

Today I wanted to boot from the ISO into recovery mode, because we accidentally lost the root password. However, rescue boot fails - grub tells me:

error: compression algorithm 68 not supported
ERROR: could not find boot disk automatically

I managed to reset the root password in the meantime - my question is: why is the rescue boot not working?

Thanks,
Andreas

Hi, I just encounter the same issue, I also want to reset the root password as failed to login after installation. I try to boot ISO and click the "Advanced options", and then choose the "Resuce boot", but it boot into normal but not shell, I still need to login. I want to chroot the filesystem and then change the root password.
