Rpi4+AlloDigiOne sig. Snakeoil os installation problem

[uglymusic]

To revive old topic - last year I tried Snake Oil on rPi4+AlloDigiOne sig. combination.Installation was successful after @agent_kith s help.  Used SO for few weeks , results were good but I always liked to have server on one machine and player on the other so I stoped using SO on rPi 4. Early this year I install SO on NUC as  server(LMS) and Picoreplayer(Squeezelite) on rPi4+AlloDigiOne sig. as player but what I really want is to have SO on rPi4 and try MPD and other players in SO.
My problem is that I can't install SO on rPi4.Tried with Raspberry OS 32bit , Ubuntu 20.4 , 22.4 , 23.4  but always get same error : 
"Checking CPU:wrong installer ,please use aarch64 installer."

Tried both SO installer but without success.Always same error.Here is screenshot:

I suppose it's a trivial problem , something like we said in my country :"Can't see the forest because of the tree."
I'd aprecciate it if you could help me.

Been there. My theory is that the latest Raspberry Pi OS has a new version of the Linux kernel, and this is causing the problems. You need to install an earlier version of Raspberry Pi OS and all should go well. I have posted about this elsewhere on this forum, but can't see the posts right now.

I'll have a look at my notes and post precisely what you need to do in the morning (I'm in the UK).
