Dear MakiseKurisu,

I am very thankful for your effort. I tried your approach several times, but I get stuck at second phase debootstrap so that aasch64-static is not found.

For your information I describe the steps and prerequisites I use:
0) I follow the script line by line to better see outputs.

1. RockPi 4B+ with armbian buster installed on EMMC so that SD-Card is free to mount and write.
2. I set the Variables to the specific values, but I do not configure WLAN since I do not need it.
3. I configure my PVE-FQDN
4. I configure my time zone and keyboard layout to my needs.

I assume, that after line #150 I got an SD-card to boot from, on which proxmox is installed.

Then, I think, I have to execute command proxmox-boot-tool.
I do not know how to do #152, but I think, this is optional? (I assume, I have to execute the commands in lines #154 and so on)

Am I doing anything wrong? Do I habe to install the kernel-headers? This should be the linux*rockchip64 ones?

Thank you for your advice, erwin1024. :-)
