I'm newbee in Linux.
I use ubuntu server and SOC intel apollo lake SOC as home
router/firewal/Nas/music server.
It worked fine (with 17.10) before upgrade...
After ubuntu upgrade I have issues with unbound, firewall (shorewall), and
Wifi network interface (hostapd dosen't start automaticaly) ;-)
How could I fix unbound issue?
Thanks,
