Blocked while installing Yunohost on Olimex Lime2

What type of hardware are you using: Other ARM board
What YunoHost version are you running: Trying to install 12 but can’t for now
How are you able to access your server: Direct access via physical keyboard/screen
Are you in a special context or did you perform specific tweaking on your YunoHost instance ?: No just trying to install yunohost

Describe your issue

I’m trying to install Yunohost on a the Lime2 from Olimex.
I was following this excellent guidelines from CBiot:
https://cbiot.fr/dokuwiki/homeserver:olinolinux

However, now with the upgrade to debian 12 of Yunohost, I’m stuck because Olimex has no Debian 12 version yet as you can see here:
https://images.olimex.com/release/a13-olinuxino/

and apparently I can’t install a previous version of Yunohost because I’m getting this message:
“This script can only be ran on Debian 12 (Bookworm).”

Do you know if I can install somehow a previous version of yunhost until olimex upgrade on their side?
The other option would be to use another light version of Debian on the board but all of them are all as well: See here in the links under Software

Do you have any idea on how this can be solved?
I’m beginner level, so any guidance with a link to a written or a video would be much appreciated.

Thank you!

This script can only be ran on Debian 12 (Bookworm).

One way of going forward is to get image based on Debian 12 (Bookworm).

The other is to install with legacy installer and migrate the system right after installation. The command to do so would be (as root)

curl https://install.yunohost.org/bullseye | bash

thanks! I have tried the second option and it’s working.

Now I have another problem: I didn’t enable the ethernet controller before installing Yunohost so when now I try to follow the guidelines of olimex :
"
Q: How to detect and enable the Ethernet controller (if it is disabled by default)?
A: You can enable it by following these two steps:

  1. To check under what name the LAN is associated write “ifconfig –a”
  2. If, for example, it is under eth0 name, then write: “dhclient eth0”
    This should enable the Ethernet and then SSH would also be available.
    You can also enable auto detection of Ethernet on power-up by removing the comment #auto eth0 in /etc/network/interfaces in the Linux image."
    it’s not working. the dhclient eth0 doesn’t change anything. And the file /etc/network/interfaces is almost empty and there is no mention of eth0.

Any work around this?

Another non-directly related question is about the possibility to have this installation on Lime2 encrypted, as I was not asked at any step if I want to encrypt or not.

Do you know how I can achieve this? Thank you
