I installed a special version of RancherOS v1.5.6 for Proxmox on Proxmox VE 5.3-6. I backup the VM and transfer it to Proxmox VE 6.4-4. On booting it up, I got the following error:
Loading ../vmlinuz-4.14-138-rancher...ok Loading ../initrd-v1.5.6...ok XZ-compressed data is corrupt -- System halted
I tried to boot up the system using this external disk image: rancheros-autoformat.iso
And it works just fine, so I can conclude that System Docker is the source of the problem. My question now is how do I repair it. I followed a set of instructions to install it on system disk initially, but if I were to install it over the current one, won’t all current settings be lost?
