you could check your kernel release with

cat /proc/sys/kernel/osrelease

or maybe

uname -r

it seems diagnostics have slight issue

Can you elaborate which board exactly ?

Also I assume you used an armbian image for the install ?

hi aleks & ynh.

i’m running via armbian image, yes, and my board is a rockchip64 from pine64, i think this one: ROCKPro64 - PINE64.

calling cat /proc/sys/kernel/osrelease outputs: 6.18.10-current-rockchip64

I’m all so dealing with this on a RPi4
