Eu tenho uma inicialização em Quad de Wandboard a partir de um cartão SD com o Ubuntu 15.10.
Depois de atualizar minha distribuição com:
$> sudo apt-get update && sudo apt-get upgrade
meu Wandboard é assim:
root@smog:~# uname -a
Linux smog 3.10.17-1.0.2-wandboard+gbe8d687 #1 SMP PREEMPT Wed Apr 1 08:46:23 UTC 2015 armv7l armv7l armv7l GNU/Linux
root@smog:~# cat /proc/version

root@smog:~# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 15.10
Release: 15.10
Codename: wily
Como você pode ver, há uma incompatibilidade entre a versão do kernel e a versão dos módulos (dos rootfs atualizados), portanto, comandos como iptables não funcionarão:
root@smog:~# iptables -L
modprobe: ERROR: ../libkmod/libkmod.c:578 kmod_search_moddep() could not open moddep file '/lib/modules/3.10.17-1.0.2-wandboard+gbe8d687/modules.dep.bin'
iptables v1.4.21: can't initialize iptables table 'filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
Por favor, note que este comando não funciona no meu caso (de aqui ):
$> sudo apt-get install linux-image-$(uname -r)

E: Couldn't find any package by regex 'linux-image-3.10.17-1.0.2-wandboard+gbe8d687'
Como faço para corrigir este problema, exceto para re-flashing minha placa com uma imagem limpa (e nunca atualizá-lo)?
